Abstract
Provided is a driving control apparatus that can control relaxation of force in an actuator. The driving control apparatus is provided with: a driving control unit configured to control driving of the actuator according to a driving control signal; and a pressure control unit configured to control, according to a pressure control signal, involvement of the driving control signal in control of pressure to be generated by the actuator.
Claims15
A driving system for an actuator, the driving system comprising:
- a driving circuit configured to drive the actuator according to a driving control signal;
- a first amplifier configured to control, according to a pressure control signal, gain of the driving control signal to be supplied to the driving circuit;
- and
- a second amplifier configured to control, according to a braking force control signal, an output impedance of the driving circuit to control a braking force generated in the actuator, wherein
- the second amplifier and the driving circuit are in a braking force control loop configured to cause the driving circuit to output a driving current according to a pressure instruction signal and control the output impedance of the driving circuit, by controlling feedback of the driving current of the actuator in the braking force control loop, and
- the first amplifier is further configured to generate the pressure instruction signal by processing the driving control signal based on the pressure control signal.
