【Abstract】 Antenna stable platform is mainly used for isolating radar antenna from carriers′ motion,so as to improve the detection effect of radar.This paper introduces design and simulation of a kind of control system for stable platform based on PLD.The control system of stable platform mainly consists of five circuits:signal gathering circuit of fiber optical gyro,signal detection circuit of encoder,drive circuit of Servo motor,interface circuit and control computer.Fiber optical gyros detects rotation of stable platform around the three axles,and PC/104 control computer analyses the gyro signals and get Servo motors working to compensate carriers’ motion.Three encoders measure the compensation errors of the stable platform,in order to realize that the antenna points stablely.The simulation result shows that the design of the control system of stable platform is correct.更多还原
