Abstract The traditional adaptive control has many problems, such as many adjusting parameters, relying on accurate mathematical model, slow convergence speed and easy to be affected by unknown interference. Therefore, it is very necessary to improve the adaptive control by combining more control methods. Taking the servo system as the object, this paper analyzes the basic principle of the compound adaptive control algorithm after the combination of adaptive control and neural network, sliding mode control, fuzzy control and other control methods, as well as the application of various algorithms in the servo system. Finally, the main shortcomings of composite adaptive control of servo system at this stage and the direction of improvement and development in the future are summarized.
