由于大多数过程具有非线性，因此在流程工业中需要控制器设计方案来处理这类系统。另一方面，PID控制器在过程系统中得到了广泛的应用。因此，本文针对非线性系统提出了一种新的基于记忆建模的PID控制器设计方案。在MB建模方法中，根据数据库中存储的被控对象的输入/输出数据对自动生成一些局部模型。该方案利用存储在数据库中的输入/输出数据生成PID参数。该方案即使在系统具有非线性特性的情况下，也能在线整定PID参数。最后，通过仿真算例对所提出控制方案的有效性进行了数值评估。
Since most processes have nonlinearities, controller design schemes to deal with such systems are required in process industries. On the other hand, PID controllers have been widely used for process systems. Therefore, in this paper, a new design scheme of PID controllers based on a memory-based (MB) modeling is proposed for nonlinear systems. According to the MB modeling method, some local models are automatically generated based on input/output data pairs of the controlled object stored in the data-base. The proposed scheme generates PID parameters using stored input/output data in the data-base. This scheme can adjust the PID parameters in an on-line manner even if the system has nonlinear properties. Finally, the effectiveness of the newly proposed control scheme is numerically evaluated on some simulation examples.
