The traditional design optimization of system parameters and a feedback controller usually follows a sequential strategy, where the open-loop system parameters are optimized first, followed by the controller design. However, this design strategy will not lead to an optimal closed-loop performance due to the coupled nature of the plant and controller optimization problems. Specifically, this two-step design methodology does not utilize the full design freedom to achieve an optimal overall system. It has been shown that the overall system performance can be significantly improved if the design process of the plant and the control system is integrated [17,18,28–30]. The integrated design strategy corresponds to a simultaneous optimization of the design parameters of both the plant and the controller to satisfy desired set of design specifications and to optimize the closed-loop system performance. Past research work has demonstrated the improved performance achieved using the integrated design strategy compared to the sequential method of design.
