Research of Sliding Mode Control in Electro-optical Tracking System
as the foundation and critical part of the free Space optical communication,the electro-optical tracking system is a typical nonlinear system.However,the angular accuracy should be better than a few micro-radians to meet the requirement of the communication link construction between two terminals.To get more control precision,the mathematic model of the coarse pointing system is founded,and sliding mode variable structure controller with approach law is designed.Finally,the simulation is done separately for a typical PID controller and the variable structure controller.Simulation results are showed that the sliding mode control can finely control the attitude of coarse pointing system,and can get higher precision by contrasted to the conventional PID controller.
