摘要/Abstract

摘要： 针对感应电机高阶非线性、强耦合等特点,提出了一种基于平衡点计算的感应电机哈密顿控制策略。基于端口受控耗散哈密顿理论,通过重新选择状态变量,构造了感应电机哈密顿结构的数学模型;采用平衡点计算的方法设计了感应电机哈密顿控制器。通过理论分析,探讨了阻尼参数对哈密顿控制性能的影响,并综合考虑系统性能确定了哈密顿控制器的阻尼参数;针对负载扰动控制问题,设计了负载转矩观测器,提高了哈密顿控制的鲁棒性。实验结果表明,提出的感应电机哈密顿控制器具有良好的转速响应速度、稳态精度和鲁棒性,为感应电机的高性能控制提供了一条新途径。

Abstract: For the high order, nonlinear and strong coupling characteristics of induction motors, Hamiltonian control strategy was proposed based on the calculated equilibrium points. Hamiltonian mathematical model of induction motor was constructed by reselecting the state variables based on port-controlled dissipation Hamiltonian theory, and then Hamiltonian controller for induction motor was designed with the method of calculated equilibrium points. Damping parameters were analyzed through theoretical analysis and determined by considering the overall performance of control system. For load disturbance problems, the load torque observer was desigened to improve the speed robustness. Experimental results showed that the new proposed Hamiltonian controller for induction motor had a good overall performance with speed dynamic response, steady accuracy and load anti-disturbance, thus Hamiltonian theory provides a new way of high-performance control for induction motor.

Key words: Hamiltonian control, calculated equilibrium points, damping parameters, induction motor, modeling and simulation
