Based on the digital simulation Composite PID controller of resonance type optical gyroscope system

The present invention relates to the control device of Circuits System stability, particularly relate to the control device for stability of optical gyroscope system, be specially a kind of digital simulation Composite PID controller based on resonance type optical gyroscope system, comprise proportion operational amplifier, integral operation circuit, differential operation circuit and ratio totalizer, also comprise FPGA control chip, the first AD conversion module, the second AD conversion module, the first program-controlled resistor, the second program-controlled resistor, the 3rd program-controlled resistor and program control electric capacity.The invention provides a kind of digital simulation Composite PID controller, adjustable resistance in original analog pid controller and tunable capacitor are transformed to the program-controlled resistor and program control electric capacity that automatically control by chip by this controller, the parameter of controller is regulated, chooses simply accurately, solve the problem that analog pid controller control mode is dumb, control accuracy is not high.
