The Variable Structure Control of Electromagnetic Vibrator

Variable structure control of electromagnetic vibrator is studied. Through the establishment of nonlinear mathematical model, it uses variable structure control to control the electromagnetic vibrator. This method can overcome the shortcomings of traditional PID control that are lack of adaptability and parameters of the controller requiring constant adjustment. The simulation results show that, variable structure control algorithm can reach the purpose of the precise control with the system parameters change or outside interference and this system is more robust.
