Controller Design for the Electrical Load Simulator Based on H∞ Control Theory

This paper took the electrical load simulator system as research object, applying H infinity control theory to the controller design for the system. After building the system model, the generalized plant was derived and the standard H infinity problem was proposed. The selecting basis of weighting function was illustrated in detail and by virtue of the Matlab robust toolbox and LMI method, the H infinity controller was synthesized. According to the simulation results, the feasibility on torque servo and surplus force suppression was verified. Finally, the advantages of H infinity control theory on improving the load simulator system performance were analyzed by comparison with classical control theory.
