Applied precise Multivariable control theory on shunt dynamic power filter using sliding mode controller

This paper presents design, analysis, simulation and application of the Multivariable control theory to a shunt dynamic power filter to augment the power quality by reducing harmonics of electrical system. The aim of this work is to linearize active shunt power filter by applying nonlinear transformation to electrical model. To achieve the improved dynamic characteristics of the electrical system, sliding mode controller is suggested which bequeaths heftiness and tactlessness to system parameters. Moreover, the suggested multivariable controller ensures the apt following of the reference signal by means of PI controller and simplifies the on the whole control design. The controller is designed and implemented in MATLAB 2012a. Simulation Results are provided in MATLAB 2012a.
