Multivariable Systems, PI control, Self-tuning Control, Robustness.
In this paper, we employed the DNA (Direct Nyquist Array) method to extend the gain and phase margins design for SISO (Single-Input/Single-Output) PI (Proportional-Integrative) controllers to the multivariable system. This design method allows us to specify the robustness and performance of a system through gain and phase margin specifications. An illustrative example is provided.
