基于端口耗散哈密顿系统的电机控制方法

Motor control method based on port dissipative Hamiltonian system

为了满足永磁同步电机高精度、高动态性能的控制要求,提出了一种基于端口耗散哈密顿系统的电机控制方法.采用系统互联和阻尼结构配置的方式对永磁同步电机控制系统进行了设计,建立了d-q坐标系下的永磁同步电机数学模型,构造了端口耗散哈密顿系统的能量函数,利用IDA-PBC方法对电机速度控制器进行了设计.仿真结果表明,提出的控制策略只需要调节两个参数即可实现对电机的速度控制,减少了系统复杂性,利用负载扰动观测器作为前馈补偿,降低了噪声影响,加快了系统的响应速度,提高了系统运行的稳定性.

In order to meet the high control requirements for precision and dynamic performance of permanent magnet synchronous motor(PMSM),a motor control method based on port dissipative Hamiltonian system was proposed.The control system of PMSM was designed by means of system interconnection and damping configuration,and the mathematical model for PMSM in d-q coordinate system was established.In addition,the energy function of port dissipative Hamiltonian system was constructed,and the speed controller of PMSM was designed by IDA-PBC method.The simulation results show that the as-proposed control strategy can realize the speed control of motor by adjusting only two parameters,which reduces the system complexity.The load disturbance observer was used as feed-forward compensation,which reduces the noise effect,speeds up the system response and improves the system stability.
