Hamiltonian Control of Permanent Magnet Synchronous Motor and DSP Implementation

为了实现对永磁同步电动机(PMSM)速度的精确控制,提出了一种利用端口受控哈密顿(PCH)方法对速度伺服系统进行控制的方法。首先,根据PMSM的PCH数学模型,求取速度控制器,并针对负载转矩未知的情况设计了转矩观测器;然后,搭建了一套基于TMS320F2812 DSP的速度控制系统实验平台;最后,通过实验对设计的控制器进行了验证。实验结果表明了该控制器能够实现电机的速度控制,并且具有良好动态性能及稳态性能,满足了PMSM高性能控制要求。

To achieve precise speed control of permanent magnet synchrotrons motor( PMSM),the port- controlled Hamiltonian( PCH) method was presented to control the speed servo system. Firstly,the speed controller was got based on PCH mathematical model of PMSM,and a torque observer was designed for the unknown load torque. Then,an experimental platform of speed control system based on TMS320F2812 DSP was constructed. Finally,the experiments were carried out to verify the validity of the designed controller. Experimental results show that the designed controller can achieve the speed control of PMSM,and the system has good dynamic performance and steady- state performance,which can satisfy the high performance requirements of PMSM control system.
