This research discusses unknown input interval observers for discrete-time wind turbine-generator systems. Firstly, the paperpresents a reliable interval observer for a linear parameter-varying (LPV) system with unknown and immeasurable parameters. Secondly, systems should be considered to jointly estimate the state and unknown inputs. To address this challenge, the study develops an interval observer for a discrete-time system incorporating unknown parameter vectors. These estimating techniques relyon the insertion of extra weighting matrices to assist in reducing the impact of system uncertainties and to guarantee the stability and cooperation of the interval observers. Examples are simulated by MATLAB/Simulink software to demonstrate the effectiveness of the algorithms.
