Design of the Vehicular Eletro-Optical Tracking Turntable Servo System and the Research on its Tracking Control Scheme

Abstract:

In order to realize the high precision tracking control of the vehicular eletro-optical tracking turntable with the car bodys vibration, it is necessary to design a high performance turntable servo system and a set of high precision eletro-optical tracking control scheme. In this paper, a digital servo system is designed, which has the control platform based on PC104 processor, has the torque motor as the actuator, has the gyro as the inertial velocity measurement tool and has the high precision encoder as the position measurement tool. Then, the gyrostabilized double speed loop control algorithm with disturbance observer compensating is designed to realize a good inertial velocity stability performace; and, a set of eletro-optical tracking compound position loop control scheme based on the target-missing quality data processing, the segmented PID control and the acceleration lag compensating control is proposed to enhance the eletro-optical tracking precision. The result shows that the tracking turntable based on the control technology designed in this paper is reliable, responses quickly, has a good speed stability performance and a high eletro-optical tracking precision performance.
