[0015] Such as figure 1 As shown, the quantification method for the control loop sensor of the spatial optical payload force disturbance simulation source actuator includes: determining the control loop type 1, determining the loop sensor type and sensitivity 2, determining the control range and minimum control step size 3 , Determine the sensor quantization bit width 4 and loop sensor gain compensation 5. Among them, the drive adopts Copley JSP-180-10, the controller adopts DSP28335, the force sensor adopts 208C02 of PCB company, the force feedback loop update control frequency is set to 10kHz, the current control command adopts the PWM method, and 100% PWM corresponds to the current command 4A. 50% PWM corresponds to the current command 0A, and 0% PWM corresponds to the current command -4A.
[0016] Such as figure 2 As shown, the specific steps of the method of the present invention are:
[0017] The first step is to determine the control loop type. The control input parameter...
