ABSTRACT
This chapter develops a load position tracking controller for the electromechanical model of a switched reluctance (SR) motor driving a position-dependent load under the assumptions that load position and stator current measurements are available and that an exact model for the electromechanical system dynamics can be determined. While the output feedback (OFB) controller for permanent magnet stepper (PMS) motor provides a starting point for the design of a partial state feedback (PSFB) controller for SR motor, the SR motor control design is more complicated due to the fact that the multi-phase SR motor/load electromechanical dynamics exhibit. A Lyapunov-like argument is used to illustrate that the open-loop observer ensure that the load velocity observation error converges to zero exponentially fast. A Lyapunov-like argument is then used to prove that all of the signals in the actual electromechanical systems and the observer remain bounded during closed-loop operation.
