基于铜耗最小原则的混合磁路电机哈密顿速度控制

针对电机传统控制策略依赖模型精确性、对参数变化敏感等问题,从能量的观点出发,利用哈密顿能量系统理论来设计混合磁路电机的速度控制器。根据铜耗最小原则下的最优电流控制原理确定了系统期望的平衡点;利用互联和阻尼配置的方法,设计了系统在负载转矩已知时的速度控制器;并利用负载转矩估计器在线观测负载转矩,由此设计了系统在负载转矩未知时的速度控制器;同时给出了平衡点的稳定性分析。仿真结果验证了该控制策略具有较好的控制效果,对系统参数变化具有较好的鲁棒性。

Speed Control of Hybrid Excitation Synchronous Motor with Port Controlled Hamiltonian Method Based on Principle of Minimum Copper Loss

There are some disadvantages within traditional control strategy of motors,such as depend on exact model,sensitive to changes of parameters,and so on.Using Hamilton energy system theory with HESM (Hybrid Excitation Synchronous Motors) based on energy viewpoint,and the speed controller was designed.First,according to the principle of minimum copper loss,the desired equilibrium of the system is obtained.When the load torque was known,the speed controller was designed using the interconnection and damping assi...
