Optimal Design and Experimental Research on a New Hybrid Electromagnetic Actuator for Vehicle

A new hybrid electromagnetic actuator (HEMA) was proposed and designed to solve the problem of reliability of linear electromagnetic actuator. A modified skyhook control was adopted to match the structure of the HEMA and the performance parameters were optimized. Then, taking the peak electromagnetic thrust of the linear motor need as the optimization objective, the structural parameters of HEMA were optimized. Finally, a prototype was developed and carried out bench tests. Results show that the hybrid electromagnetic actuator can improve the vehicle dynamics performance, verifying the effectiveness of the prototype.
