摘要
基于模糊逻辑控制的速度控制器,其速度误差和速度误差变化率信号经量化因子转化后,通过规则评价和解模糊运算得到增量式输出。再定义输入输出变量的模糊子集数,采用mamdani极小法及加权平均法进行解模糊运算。该控制器以规则库离线设计制成模糊规则表,在线时采用查表的实现。通过Matlab/Simulink仿真并与PI控制系统速度响应比较表明,模糊控制有较强鲁棒性和优越的调速性能。
The speed controller based on fuzzy logical control, with its speed error and speed error rate of change signal after the quantification factor transformation, the fuzzy logic speed controller obtains the increase type output through the rule appraisal and de-fuzzication operation. Again defining the fuzzy subset number of the input and output variable, and using the mamdani minimum method and weighted average method to de-fuzzy. According to the ruler base＇ off-line design, this controller can be carried＇out as a rule list which can be looked up online. A comparison between the Matlab/Simulink simulation and PI control shows that the FLC can receive a good robustness and speed control characteristics.
