Design of Compensating Algorithm for High-accuracy Position Follow-up Control System

This paper discusses two control strategies of high-accuracy follow-up control systems.Taking a positon servosystem as example,the paper introdeces the method of distinguishing the error interval which is the basis for the selection of control strategy,then a new compensating algorithm based on decelaration control is demonstrated and simulated.The results show the steady-state properties of the control system is improved and the steady-state error decreases.
