Deadbeat Predictive Current Control of Permanent Magnet Synchronous Motor Based on Disturbance Observer
摘要
Abstract
The favourable current control was required in speed or torque drive system of permanent magnet synchronous motor,so it's very important for the control of the current loop.In order to improve the transient performance and the robustness,a novel current control method based on deadbeat predictive control and disturbance observer was proposed.By using the good transient response and easy digital realization of predictive control,the current controller was designed based on deadbeat theory,which was greatly dependent on the motor model and the parameters.According to the disturbance caused by the modeling error and parameter variations,a simple disturbance observer was designed,which was used for the feed-forward compensation control.The robustness was enhanced effectively.The experiment was complemented on dSPACE,and the results showed that the proposed current control method had good current tracking and strong robust performance in various conditions.关键词
