H ∞ Controller Design for Induction Motor to Attenuate Rotor Resistance Perturbation and Torque Disturbance with Field Oriented

摘要: It is well known that the system performance of field oriented control induction motor drives degrades under variation rotor resistance and in presence external load torque disturbance. H infin state feedback method employed to design controller for fed by a current controlled voltage source inverter this paper. The proposed law can achieve convergence zero both speed flux tracking errors ensure robustness with respect disturbance variation. In some sense, be regarded as PI studying its structure, from Hinfin, point view, result explains why controllers have been used successfully partially. Another important contribution it presents useful way robust controller. Simulation results are given validate
