Backstepping Control Based Maximum Torque Per Ampere Control of Permanent Magnet Synchronous Motor for Mechanical Elastic Energy Storage
摘要
Abstract
In contrast with id=0 control, maximum torque per ampere control enables permanent magnet synchronous motor to output a larger low-speed torque and has a better dynamic performance under equivalent capacity. It is extremely suitable as the drive control for mechanical elastic energy storage system. A backstepping control based maximum torque per ampere control approach is proposed for permanent magnet synchronous motor. The relation equation of minimum d-axis and q-axis currents in maximum torque per ampere control is constructed through extremum principle. Simultaneous variations of torque and inertia for spiral torsion spring load are estimated through least square algorithm with forgetting factor. Conventional PI controllers of speed and current are replaced by designed backstepping controllers of speed and current respectively, and the stability of the proposed algorithm is proved in theory. Experimental results indicate that the proposed approach requires less stator current in comparison with backstepping based id=0 control. Additionally, the approach has the advantages of prompt tracking reference signals, good dynamic performance and fewer parameters adjustment.关键词
