Feedback Linearization and Decoupling Control of Induction Motors

  • A new control strategy was proposed to decouple magnetic flux linkage in the rotor from speed into two independent linear subsystems, namely,Φ=φrα2+φrβ2, The decoupled system can be solved with the linear quadratic optimal control theory.The designed control law is globally defined without singularity, ensuring asymptotically tracking the magnetic flux linkage in the rotor, speed, and torque.A simulation example demonstrates the feasibility of the proposed strategy.In the simulation, the magnetic flux linkage keeps constant while the rotor speed changes, and the system shows good dynamic and static performances.
