论文摘要
本文有助于设计一阶和时间延迟(FOPTD)过程模型的分数订单(FO)内部模型控制器(IMC),以满足给定的一组所需的鲁棒性规范,以增益余量(AM)和相位微量边缘(PM)。该设计的亮点是在IMC结构中选择一个分数阶(FO)滤波器,该滤波器具有两个参数(lambda和beta),与传统使用的整数(IO)滤波器仅一个调谐参数(Lambda)相比,可以调整两个参数(lambda和beta)。对控制器评估了这些参数,因此可以独立选择AM和PM。提出了一种新方法来找到用于控制器参数的完整解决方案,该方法还提供了系统增益交叉频率(WG)和相位交叉频率(WP)。此外,发现解决方案没有任何延迟项出现在控制器中的任何近似值。
This paper contributes to the design of a fractional order (FO) internal model controller (IMC) for a first order plus time delay (FOPTD) process model to satisfy a given set of desired robustness specifications in terms of gain margin (Am) and phase margin (Pm). The highlight of the design is the choice of a fractional order (FO) filter in the IMC structure which has two parameters (lambda and beta) to tune as compared to only one tuning parameter (lambda) for traditionally used integer order (IO) filter. These parameters are evaluated for the controller, so that Am and Pm can be chosen independently. A new methodology is proposed to find a complete solution for controller parameters, the methodology also gives the system gain cross-over frequency (wg) and phase cross-over frequency (wp). Moreover, the solution is found without any approximation of the delay term appearing in the controller.
