| 摘 要： | 首先利用无源性理论,构造自适应反馈控制器使具有v/f控制输入的混沌永磁同步电动机(PMSM)等效为闭环无源系统,然后证明该无源系统可以实现在平衡点的稳定,从而达到镇定PMSM混沌运动的目的.数值仿真结果表明,该控制策略不仅行之有效,对参数的不确定性具有较强的鲁棒性.研究结果对保证具有v/f控制输入的PMSM的稳定运行有较好的参考价值.

| Abstract: | A passivity-based adaptive control law is presented, which transforms the permanent magnet synchronous motor (PMSM) with v/f controller into an equivalent passive system. It is proved that the equivalent system can be asymptotically stabilized at different equilibrium points without any influence of undeterministic parameters. Simulation results show the proposed control law is very effective and robust against the uncertainty in system parameters. |
