Problems solved by technology

Therefore, when the deviation has a large amplitude, the use of the double closed-loop control method will easily cause integral saturation. In the case of a sudden change, a large overshoot phenomenon occurs, and even causes system instability

Abstract

The invention provides a transient process-based anti-integration saturation design method and belongs to the field of photoelectric system tracing control. Aiming at the problem that an integral saturation phenomenon occurs in a conventional dual-closed loop control method during tracking a phase step reference signal to cause excessively large system output overshot and stability reduction, themethod for designing transient process is proposed for the integral saturation phenomenon. After the transient process and the dual-closed loop control method are effectively combined, the purpose ofanti-integration saturation is achieved, the rapidness of tracking the phase step reference signal by dual closed loops is maintained, meanwhile, the system stability is improved, and the problem of large overshot during tracking is solved. By experiment of the photoelectric tracking system, the effectiveness of the method is verified.

Description

technical field [0001] The invention belongs to the field of photoelectric system tracking control, and specifically relates to an anti-integral saturation design method based on a transition process, which applies the transition process to a double closed-loop control method, effectively solves the phenomenon of limited input, and fully improves the tracking performance of a photoelectric system. Background technique [0002] The photoelectric tracking system includes main control, servo, image, signal transmission and other sub-systems. After receiving the target position signal sent by the main control unit, the servo system drives the motor to perform fixed-point tracking; during the control process, as the system error decreases , the target will gradually appear on the tracking sensor. Its control system usually consists of a speed inner loop and a position outer loop to form a double closed-loop structure. The function of the speed inner loop is to obtain a speed con...
