摘要： The present invention relates to a control system for a servomechanism device such as robot, and more particularly to a position correcting control system for a servomechanism device which is well suited to perform high-precision positioning or high-perfomance operations on the basis of a sensor feedback control system such as force detection feedback control. It is characterized in that a plurality of algorithms for correcting a position target value on the basis of a sensor signal are prepared and are switchedly used so as to readily switch functions, depending upon whether the purpose of a sensor control is a high-precision control or any other high-performance control, that the position target value is corrected through a threshold characteristic element or a dead band element so as to make effective the correction of the position target value based on the sensor signal, and that a correcting signal is applied through a response lag element so as to attain stabilization owing to a viscous effect bestowed on the position correcting operation based on the sensor signal.

摘要： The two secondary windings of a transformer the primary winding of which is connected to an AC power supply are each provided with a controlled rectifying circuit. The DC sides of the rectifying circuits are connected in series to supply power to DC motors. One of the secondary windings is detachably connected with a capacitor bank. The capacity of the capacitor bank is selected so that the power factor of the converter can be improved to a satisfactory value when the two rectifying circuits are both controlled to produce output voltages. The capacitor bank becomes connected in response to the fact that the current in the primary winding of a transformer has arrived at a predetermined value.

摘要： A power converter control apparatus comprising continuously controlled converter units and on-off controlled converter units for effecting powering control and regenerative braking control of a DC motor, which is arranged to include a unit change circuit for generating unit changing operation signals in response to a command for instructing the number of the converter units to be rendered operative from a master controllerand conduction phase signals from a phase shifter. In accordance with the unit changing operation signals, the conduction phase signals from the phase shifter are applied as a gate signal to the continuously controlled converter units in response to a powering control or a regenerative braking command, while a minimum conduction phase signal is applied as a gate signal to the on-off controlled converter units in response to a powering control command signal and a maximum conduction phase signal including a commutation marginal angle in response to a regenerative braking command signal. On the other hand, the gate signals supplied to the continuously controlled converter units may be temporarily cut off by a gate cut-off circuit and at the same time the conduction phase in the output of the phase shifter may be restored.

摘要： A power converter system comprises a connection of a plurality of controlled rectifiers and a plurality of uncontrolled rectifiers, or a connection of only a plurality of controlled rectifiers. With an AC power supply as an input, the firing phase of the controlled rectifiers is controlled for conversion into a desired power. The commutating operation of the rectifiers is performed by utilizing the AC power supply. A retardation coil is connected to each of the rectifiers connected in series in the same polarity and making up an arm of the connection. The thus connected retardation coils are magnetically coupled with each other. The inductance of the commutating circuit is smaller when the output of the power converter is substantially maximum or minimum than the inductance when the output of the system is not maximum or minimum, thereby effectively reducing the higher harmonics components of the AC input current of the system at the time of commutating operation of the rectifiers without reduction of the utility of the converter.
