摘要： In a holding arrangement (101) for a medical-optical instrument (103), an electric motor is provided in a rotational joint (111, 119) to compensate a load torque occurring in this rotational joint. This electric motor is supplied with current in correspondence to a detected position of the rotational joint (111, 119). A current control curve required for this purpose is stored in a memory. This current control curve can be determined in that the rotational joints are deflected with the electric motor into predetermined positions and the current demand needed therefor is detected. The holding arrangement (101) has a unit for actively damping vibration including a vibration damping control loop. This vibration damping control loop outputs a superposition motor current to the electric motor as an actuating quantity in order to move the rotational joint (111, 119) with the electric motor so that a detected vibration of the holding arrangement (101) is countered.

摘要： A table containing correspondence between “n” and “m” is set in a control circuit of a servo control system so that the current command data in the m-th (m=1, 2, 3 . . . ) current command register is assigned to the n-th (n=1, 2, 3 . . . ) servo amplifier. When data is specified in this table to satisfy “n=m”, the current command data in the n-th current command register is passed to the n-th servo amplifier. When “m=1” is set for “n=1” and “m=1” is set for “n=2” in this table, the current command data stored in the first current command register is passed to the first and second servo amplifiers.

摘要： An improved position control for a solenoid actuated valve, wherein the solenoid is activated based on the combination of a feed-forward component based on a model of the steady state operation of the valve and a closed-loop feedback component that responds to changes in the commanded position and compensates for any inaccuracy in the steady state model. The method involves a valve characterization procedure in which the actual force generated by the solenoid is measured for various combinations of valve position and solenoid current, resulting in a table of coil current in terms of developed force and valve position. In operation, the model is used to estimate the solenoid force required to achieve the commanded valve position under steady state operating conditions, and a controller addresses the table to obtain a feed-forward coil current command as a function of the commanded valve position and the estimated solenoid force. The feed-forward command is combined with a closed-loop feedback coil current command, which in turn, is used to develop a corresponding PWM duty cycle, given the solenoid temperature and the magnitude of the supply voltage.

摘要： A method and system are provided for positioning a gasoline engine throttle in response to an angular position input command signal. A multi-phase variable reluctance motor positions the throttle in response to motor current commands from a micro-controller. The micro-controller receives and processes the position input command and throttle position feedback signals from a multi-phase variable inductance position encoder rotatably coupled with the motor shaft. The motor current command are obtained from look-up tables that are derived from empirical data of the motor. The motor current command tables are a mapping from motor rotor position and desired motor torque to desired motor currents in the appropriate phases of the motor to hold the load.

摘要： A control unit (75) for controlling a first state variable of a system, for example an angle of rotation .phi. of a throttle valve (7) in a throttle device for use in an internal-combustion engine, the system being influenced by a disturbance variable during operation, for example an oscillating loading torque caused by air-flow fluctuations in the throttle device. The control unit includes a disturbance observer (125) for calculating a value of the disturbance variable at a first point in time on the basis of a mathematical model of the system, and a disturbance predictor (128) for predicting a value of the disturbance variable at a second point in time which follows the first point in time by a predetermined time interval. In this manner, a phase shift between the disturbance variable actually influencing the system and the compensation provided by the system for the disturbance variable is prevented at high frequencies of the disturbance variable.

摘要： A method and system for determining absolute rotor position with a Variable Reluctance (VR) motor. An inductance sensor is compatible with the VR motor and is adapted to generate a plurality of variable inductance values corresponding to the position of the rotor. The inductance values may be plotted during calibration as phase-separated pseudo-sinusoidal waveforms with a resultant inductance/position profile having near-linear regions with determinable slopes and offsets. Excitation electronics converts variable inductance values to corresponding digital values which are suitable for computer processing. A micro computer is adapted to determine which of the digital values is a mid-value and to convert the mid-value to high resolution motor rotor angular units in accordance with the calibration-determined slopes and offsets.
