A precision motion control system of linear displacement stage is designed and implemented, and the mathematical models of the parts of the linear stage control system are described. On the base of the analyses of conventional PID control, to achieve high precision requirement of linear displacement stage on position, response and moving direction, a single neuron adaptive PID controller for precision linear displacement stage is presented, and the precise motion control of linear displacement stage is realized. The experimental results show that the control system has better dynamic performance, self adaptive ability and stronger robustness.
