Abstract

With the aim to provide a high performance servo control for photoelectronic tracking systems

a simple Variable-structure PI controller(VSPI) is presented by combining the traditional PI controller theory and the variable-structure idea

then the principles of the controller are introduced and its design parameter selection is also discussed. Based on the structure of a photoelectronic tracking system

the servo control systems by using VSPI

Anti-windup PI controller(AMPI) and Integral Separation PI controller(ISPI) are simulated

respectively

and the experiments on positioning tracking and equivalent sine tracking are also carried out. The experimental result shows that the system with VSPI controller has no overshoot and its rise time

settling time and tracking precision are 0.378 s

0.488 s and 1.26

respectively. Compared with the systems using other two algorithms

the system with VSIP can complete real time control and can offer better comprehensive performance

which completely satisfies the requirements of photoelectronic tracking systems for high precision and fast response.
