摘要
提出在PMSM直接转矩控制系统中,采用解析模糊控制状态选择器替代传统的空间电压矢量选择器的新型控制方法,设计完成了基于DSP(TMS320LF2407A)为核心的全数字模糊直接转矩控制系统。在传统的直接转矩系统的基础上,磁链和转矩的调节均采用模糊控制策略,且模糊控制规则解析生成。仿真实验结果表明该控制方案可行,有效地避免了传统直接转矩控制系统在起动和转速突变时,响应不够快且转矩脉动幅度大的缺陷。系统具有良好的动静态性能与鲁棒性。
A new all-digital fuzzy direct torque control servo system of PMSM based on DSP(TMS320LF2407A) is designed and constructed, in which the traditional space voltage vector selector is replaced by an analytic fuzzy control state selector. Based on the conventional direct torque control system, the adjusting of magnetic linkage and torque both adopt fuzzy control strategy and fuzzy control rule is generated in an analytic way. The simulation experiments result show this control scheme is feasible, and the disadvantages of the conventional direct torque control system are avoided effectively, which the response is not quick enough when the system is start-up or the rotate speed breaks as well as big pulstion amplitude of torque. The system has good robust and good static-dynamic performance.
