摘要： PROBLEM TO BE SOLVED: To provide a transmission function estimation device, a transmission function estimation method and a transmission function estimation program capable of reducing an arithmetic operation load, and accurately calculating the transmission functions of an entire system.SOLUTION: An estimation formula for estimating a transmission function of an object to be measured is acquired (S101), and frequency response characteristics as data of a frequency area are acquired (S102). Whether the arithmetic operation of the estimation formula is addition/subtraction or multiplication/division is determined for each arithmetic operation (S103), and if the arithmetic operation is determined to be addition/subtraction (S103: YES), time response characteristics g, gare calculated by converting frequency response characteristics G, Gto be added/subtracted from a frequency region into a time region (S104), and the addition/subtraction of the time response characteristics g, gis operated in the time region (S105). Then, the calculated addition/subtraction result g+gis reconverted into the frequency region to obtain G+G(S106). Thus, it is possible to perform the arithmetic operation of the estimation formula for estimating the transmission functions of an entire system without calculating the transmission function of a partial system.

摘要： PROBLEM TO BE SOLVED: To easily obtain a non-interference control that reduces an influence by mutual interference between outputs in a control system controlling a control target outputting a plurality of control amounts.SOLUTION: A control system 10 calculating an input to a control target 20 of m inputs and n outputs (m=n where m and n are a positive integer of 2 or more) is configured to set a combination of an input and an output. A feedback controller 13 calculates control inputs ν1, ν2...νn to a non-interference controller 14 for each set combination so as to track a current value to a target value on the basis of a deviation between the target values r1, r2...rm of control amounts y1, y2...yn and the current value. The non-interference controller 14 implements non-interference control for each set combination so as to reduce an influence by mutual interference between n pieces of control amounts y1, y2...yn. Accordingly, since the number of combinations of the input/output, which should consider interference, can be largely reduced, the non-interference control can be easily obtained.

摘要： PROBLEM TO BE SOLVED: To improve the feeling of operation without the need of final tuning work in the case where a mechanism giving a strong inertia torque exists near a steering wheel in a steering system of EPS1. SOLUTION: According to the EPS1, an assist motor 2 forms the working point of the inertia torque in the steering system on the side of steered-wheels relative to the side of a torque sensor 5, and a microcomputer 23 includes a correction means 30 for correcting the sum of a basic assist current-carrying amount and an inertia compensation current-carrying amount. In addition, the correction means 30 calculates a correction amount according to the steering wheel-side inertia torque and add the correction amount to the calculated value of an adding means 29. By this way, mutual interference between the basic assist current-carrying amount and the inertia compensation current-carrying amount, which results from the structural characteristics of the torque sensor 5, can be alleviated so that the feeling of the operation can be improved without the need of the final tuning work even in the case where the mechanism or the like giving the strong inertia torque exists near the steering wheel in the steering system.

摘要： PROBLEM TO BE SOLVED: To provide a motor drive device that comprises a plurality of systems of inverter sections and when any inverter section fails, cuts a power supply relay connected to the fault system of inverter section to stop power supply, which prevents a circuit element on the fault system from being broken by an inductive voltage generated by a motor due to rotation by external force.SOLUTION: In a motor drive device, when failure detection means 71 detects a failure of an inverter section 50 at a first system, drive control means 41 stops driving of the inverter section 50, and opening/closing control means 31 turns off a first power relay 21 and turns on a second power relay 22, of the power supply opening/closing section 20. While driving of the inverter section 50 is being stopped, an inductive voltage generated in a first winding group 80 of a motor 800 due to rotation by external force passes from the inverter section 50 through the second power relay 22 and further passes through a parasitic diode of the first power relay 21 to return to a battery 15. This prevents breakage of a circuit element on the broken system.

摘要： PROBLEM TO BE SOLVED: To provide a compact and lightweight steering control system for preventing breakage of a component.SOLUTION: An ECU 40 calculates a basic transfer ratio on the basis of a steering angle detected by a steering angle sensor 31. The ECU 40 calculates a corrected transfer ratio by correcting the calculated basic transfer ratio on the basis of a position of a rack 6. Specifically, the ECU 40 calculates the corrected transfer ratio by correcting the basic transfer ratio so that a value of the basic transfer ratio is reduced as the rack 6 moves from a predetermined first position near one end of a moving range to the side of the one end or as the rack 6 moves from a predetermined second position near the other end of the moving range to the side of the other end. The ECU 40 determines either the basic transfer ratio or the corrected transfer ratio as the transfer ratio on the basis of the position of the rack 6. The ECU 40 controls drive of a first actuator 22 on the basis of the determined transfer ratio.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle dynamic control device that can perform a vehicle dynamic control by selecting a more optimal controlled object according to availability of the controlled object.SOLUTION: When performing the vehicle dynamic control in the lateral direction to provide an application request value by controlling a plurality of different controlled objects, a priority of the controlled object used for the vehicle dynamic control in the lateral direction based on availability is determined by transmitting availability (controllable range containing the maximum control amount and a change amount of the control amount) of each controlled object to VLP, or in more detail, an F/F computing part 6 or an F/B computing part 7 of VLP. Thus the priority of the controlled object used for vehicle dynamic control in the lateral direction is determined by adding availability of each controlled object, so that the vehicle dynamic control in the lateral direction can be performed by selecting more optimal controlled object according to availability of the controlled object.

摘要： PROBLEM TO BE SOLVED: To provide a compact and low-cost multi-system motor drive unit capable of suppressing operational fluctuation when any one of systems therein fails.SOLUTION: When a first system fails at a time t0 in a dual system motor drive unit, a power supply relay is interrupted, and output current of an inverter becomes 0 (a). A power control means doubles a current supplied to an inverter of a normal second system, as compared with during normal operation, so as to compensate for the electric power supplied by an inverter of the first system (b), and keeps the total inverter output constant before and after the failure (g). Thereby, operational fluctuation can be suppressed. Furthermore, after an elapse of a predetermined period (at a time tX), the electric power supplied by the second system is gradually reduced. Thereby, a time period while the inverter of the normal system is under excessive load is shortened. Thus, a large inverter does not need to be used, and the electric motor drive unit can be compact and low in cost.

解决方案：当双系统电机驱动单元中第一个系统在时间t0故障时，电源继电器中断，变频器的输出电流变为0（a）。功率控制装置与正常操作相比，将提供给正常第二系统的逆变器的电流加倍，以补偿由第一系统（b）的逆变器提供的电力，并保持总逆变器输出故障前后不变（g）。由此，能够抑制运转波动。此外，经过预定时间段（在时间tX），由第二系统提供的电力逐渐减小。因此，正常系统的逆变器处于过载状态的时间段缩短。因此，不需要使用大型逆变器，电动机驱动单元的结构紧凑，成本低。版权所有（C）2012，JPO＆INPIT
