Results on H-Infinity Static Output-Feedback Control of an Electro-Mechanical System

This paper presents H-Infinity static-output feedback controller implementation comparison results on an electromechanical system test bed. In eletro-mechanical systems it is expensive and sometimes difficult to achieve and implement full state-feedback. Uncertainties in the electromechanical systems and the disturbances affect the performance of the optimal controller ; controllers may require prescribed desirable structures as well. In this paper simplified necessary and sufficient conditions are revisited for static output-feedback control for a spring mass damper electromechanical systems. This paper shows implementation of a numerically efficient solution algorithm to solve coupled design equations to determine the H-Infinity output-feedback gain. No initial stabilizing output feedback gain is needed. Effectiveness of the proposed method is demonstrated through comparison of optimal output-feedback, H-Infinity output-feedback and state feedback implementation on spring-mass damper electromechanical system.
