The Research on Servo Control Technology of O-E theodolite Based on Angular Acceleration Sensor
A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control, and adopts acceleration delay compensation based on velocity delay compensation, then achieves servo control of O-E theodolite effectively. Furthermore, Angular acceleration sensor is applied as information resources, and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite, the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods, this servo control methods can improve significantly tracking precision and stability of O-E theodolite.
