Research on new fractional PID control of linear motor

Abstract

Linear motor is widely used in industry and life because of its high precision, easy control and simple structure. The control strategy of linear motor has a direct impact on its speed and accuracy, so the research on its controller is of great significance. Considering the influence of environmental noise in the application of linear motor, this paper proposes a new fractional PID controller with fast response speed, small steady-state error and strong anti-noise interference ability.
