The paper shows the design of a robust control structure for the speed sensorless vector control of the IM, based on the mixed sensitivity linear parameter variant (LPV) Hâ?? theory. The controller makes possible the direct control of the flux and speed of the motor with torque adaptation in noisy environment. The whole control system is tested by intensive simulations and according to the results shows good dynamic and robust performance. Implementation issues based on a DSP TMS320F243 development platform are also presented.
