Compensation of input and output disturbances for MIMO discrete-time systems with unmeasured state vector

Cong Vinh Tu, Natalia Dudarenko

Abstract


This paper addresses the challenge of compensating for external disturbances in a class of discrete-time linear multi-channel systems subject to both input and output disturbances. It is assumed that while the external signals have known parameters, the system states and external disturbance states cannot be directly measured. To address this challenge, the approach combines Francis' equation with a discrete-time PID observer. A full-order observer, referred to as the Discrete-Time PID Observer, is developed to estimate the state vectors. Based on Francis's equation, a regulator is designed to effectively control the output signal to track the reference signal. The effectiveness of the proposed solution is validated through MATLAB Simulink simulations.
