Abstract: The paper presents a design technique for proportional integral (PI) robust current and speed controllers of switched reluctance motor (SRM) drives. The variations of stator inductance, equivalent resistance, moment of inertia and coefficient of friction are considered leading to uncertain plant representation of the drive. Robustness of the controllers is achieved through Kharitonov theorem considering parameter uncertainties over wide ranges of operation. To attain best performance, the design is cast as an optimisation problem solved by particle swarm optimisation (PSO) to ensure maximum possible degree of stability. Extensive comparisons with the classical methods are carried out showing noteworthy advantages of the proposed routine.

Keywords: robust control; switched reluctance motors; SRM; Kharitonov theorem; swarm intelligence; particle swarm optimisation; PSO; stator inductance; equivalent resistance; moment of inertia; coefficient of friction.
