Study on the control method of medical rehabilitation robot

Since the development of twenty-first Century, the theory and methods of robot control have become more and more mature. With the continuous development of control methods, various kinds of controllers have been innovating and breaking through the production. The performance of the control devices is becoming more and more powerful and the price is getting cheaper and cheaper. In terms of robot control methods, the robot control method can be divided into two categories: PID control method and control method based on robot dynamics model. In this chapter, the feasibility analysis of the control method of rehabilitation robot is discussed, and the control effect of the rehabilitation robot control system is optimized by adding fuzzy control on the basis of sliding mode variable structure.
