摘要: 采用模糊逻辑理论设计了一个专家系统来实时监控一个多变量过程的闭环响应特性，通过在线调整滤波时间常数来改善其闭环特性，同时监控其积分平方误差指标，一旦超越某个限度，就对系统重新进行辨识．仿真实验显示了该方法的优越性．Abstract: An expert systemt hat incorporates with fuzzy logic is implemented to monitor inreal time the close loopper formance of a multiv ariable process. The expert system adjusts the filter time constants to improve the performance of close loop. If the performance,measured on the integral squar eerror,exceeds acerta invalue the expert system suggests areidentification of the process. The simulation shows anoticeable improvement in the performance of the close loop when using the expert system.
