摘要
为提升两相混合式步进电机的控制性能,建立一种基于模糊控制在线参数调节控制策略的两相混合式步进电机数学模型。在合理简化和线性化处理的基础上,采用先进的模糊控制理论和PID控制结合的控制策略,将模糊控制对环境的适应性强,可在线调整控制参数应用于对PID参数的实时调节。在Matlab仿真环境下进行建模与仿真,对比分析了常规PID与模糊PID控制的仿真特性。仿真结果表明:在不同响应和精度要求的两相混合式步进电机控制系统中,通过模糊参数在线调节控制比常规参数PID控制可以达到更优的技术指标,实现了对两相混合式步进电机的快速精确控制。
In order to improving control performance of two-phase hybrid stepping motor, its modeling was set up by one of fuzzy control parameter on-line adjusting control tactic. It was based on logical predigesting and linear disposing, combine advanced fuzzy control theory and PID control tactic were adopted, fuzzy control has better adaptability on-line adjusting control parameter was applied to PID parameter real-time adjusting. Modeling and simulation under Matlab environment was set up, simulation characteristic of general PID and fuzzy PID was analyzed. Simulation of result show, with different response an precision in two-phase hybrid stepping motor control system, fuzzy parameter on-line adjusting could be realized better technical index, it was realized fast precision control in two-phase hybrid stepping motor.
