Multivariable Control by Partial Periodic Output Feedback

This work proposes a new method for simplifying periodic output feedback control for multivariable systems with more number outputs than inputs. The computational complexity of the conventional method arises from the requirement of periodic output feedback control using all the outputs. This study demonstrates that stability can be guaranteed with only partial periodic output feedback and static output feedback from some of the output. Due to its substantial reduction in computational burden compared to the traditional complete periodic output feedback approach, this method is less computationally expensive for controlling complicated multivariable systems.
