Design of LQR based PI controller with optimum selection of weights for Time Delay Process

In this paper, an optimal PI Controller has been designed using continuous Linear Quadratic Regulator (LQR) theory for the application of first order plus time delay (FOPTD) systems. In general, time delays can limit and deteriorate the achievable system performance and induce stability. To achieve the optimal performance the LQR PI controller is designed, the selection of weight matrices Q plays ...
