Robust control for a tracking electromechanical system

Abstract

<p>A strategy for the design of robust control of tracking electromechanical systems based on 𝐻∞ synthesis is proposed. Proposed methods are based on the operations on frequency characteristics of control systems designed and developed using the MATLAB robust control toolbox. Determination of the singular values for a transfer matrix of the control system reduces the disturbances and guarantees its stability margin. For selecting the weighted transfer functions, the basic recommendations are formulated. The efficiency of the proposed approach is verified by robust control of an elastically coupled two-mass system whose parameter values are adjusted by matching them with the parameters of one of the supplied robots. The simulation results confirm that the proposed strategy of design of robust control of two-mass elastic coupling system using the 𝐻∞ synthesis is very efficient and significantly reduces the perturbation of parameters of the controlled plant.</p>

Mixed H₂/H_∞ robust controllers in aircraft control problem

“…Beisenbi and Basheyeva [29] describes the application of the Lyapunov function to construct robustly stable aircraft control systems. Karimtaevna and Asylbekkyzy [30] outlines a design methodology and implementation of robust control using H∞ synthesis tools, which allows to cope more effectively with parameters and load perturbation. The research conducted in Karimtaevna et al [31] delves into a meticulous investigation of the H2 and H∞ synthesis methods, specifically exploring their potential in the realization systems responsible for controlling the flight of an aircraft during the crucial landing phase, while effectively mitigating the impact of external disturbances.…”
