High-performance decoupling control techniques for various rotating field machines

This paper presents a comparative study of different field-oriented rotating-field machines, including squirrel cage induction machines, series-connected wound rotor induction machines, and synchronous machines. Evaluation of various field-oriented rotating-field machines for high-performance applications is presented. The concept of torque linearization and decoupling control is studied and compared for the various field-oriented motors. Computer simulations, experimental results and space phasor diagrams are employed to illustrate the dynamics of decoupling control for the various field-oriented-control (FOC) systems. The control complexity and parameter sensitivity of various FOC drive motors are compared.<
