Zero Vibration On–off Position Control of Dual Solenoid Actuator

Solenoids are low-cost high-speed nonlinear actuators commonly used in switching mode. This paper presents a dual-solenoid actuator system for high-speed positioning applications. A novel control method that combines on-off control and input shaping is used to obtain low-vibration smooth transients when compared with traditional proportional and integral control and on-off control. Simulation results and experimental data confirm that this dual-solenoid position actuator with the novel control method is effective and practical.
