Direct Thrust Force Control of Half-open Winding Linear Motor Based on Inverter Compensation
摘要
Abstract
To suppress the generation of zero-sequence current in a half-open winding linear motor system,we propose a direct thrust force control(DTFC)based on nonlinear inverter compensation.First,we analyze the operation mechanism of the zero-sequence current of the half-open winding linear mo-tor.Second,we design a DTFC strategy based on a new switching table and then introduce a nonlin-ear inverter compensation.Finally,we verify the proposed DTFC by simulation experiments.Results show that the proposed DTFC can suppress the generation of zero-sequence current and improve the operation efficiency of the half-open winding linear motor system.The coefficient of zero sequences'current suppression performance of the proposed DTFC is about 0.07,indicating its good steady-state performance,excellent self-starting performance,and transient performance.关键词
