Designing a PID Controller Using the Root Locus Method
In this video we discuss how to use the root locus method to design a PID controller. In addition to discussing the theory, we look at Matlab tools to enable this workflow. In addition, we demonstrate the effectiveness of the resulting controller on a real system. Finally, we discuss how this approach is generalizable to designing any linear controller.
