A Method to Suppress the Current for High-Power Electromechanical Actuator

In order to ensurethe current of high-power electromechanical actuatorcould be suppressed effectively and keep its fine-dynamic performance, the operation principle of high-power electromechanical actuator and its high current was studied.After analyzing the limitation of tradition current loop for suppressing the current, a segment control method of current loop was designed by online controlling the current loop parameters based on the characteristic of the electromechanical actuator dynamic response process current.Both experiment and simulation results shows that the method can suppress the current effectively and also can improve the reliability and keep the fine-dynamic performance.
