“…However, a major disadvantage of SRM is the large torque ripple especially during lower speeds, which produces intensive and undesirable vibration, acoustic noise and limits the overall application performance. To mitigate these drawbacks, many researchers have proposed solutions to enhance machine performance (see [2], [3] and [4]). However, high quality performance over a wide range of operation is still a challenge due the strong non-linear characteristics and natural parameter variations that arises from the double salient topology and the operation under saturation conditions.…”

This paper presents the results from a design study on the feasibility of a speed loop controller employing Linear Matrix Inequalities (LMI) in order to improve the disturbance rejection of Switched Reluctance Motors (SRM). The novel resulting solution benefit from a simple state feedback topology tuned previously for operation at an entire polytopic region of uncertainty and yet has a low computer effort profile allowing the solution to fit most of digital controlled drivers' platforms. Simulations and experimental results demonstrate the potential of the design. The benefits of the proposed improvement were compared with traditional PID controller dynamic response

“…However, in order to achieve improved efficiency, the SRM is supposed to operate with high magnetic saturation. This effect associated with the current level and the variation of magnetic reluctance with regard to rotor position result in highly nonlinear functions of all the machine relevant characteristics [1]- [3].…”

This paper describes the development of a self-tuning control scheme applied to the current loop of a Switched Reluctance Motor (SRM) drive for trajectory tracking. The proposed control technique is based on the minimization of a modified version for the quadratic performance index, which includes an additional weighted derivative term. The self-tuning control action is implemented using a recursive identification procedure with a covariance matrix reset scheme in order to find optimum parameters for the process. The proposed method is simulated and compared with the conventional PI controller, so often found in this kind of system, and also Ziegler-Nichols (ZN) tuning method. It must be mentioned that conventional PI and PID controllers are only able to assure optimum performance around a fixed operation point, as they have proven to be inadequate to compensate for parametric uncertainties, oscillatory dynamics, and other eventual changes in the system itself. A hardware prototype is then implemented and experimental results regarding the SRM drive show that the self-tuning controller provides a significant improvement in the system behavior, with setpoint tracking and increase the torque ripple damping.

“…At low speeds, current profiling may be utilized to reduce torque ripple. Several researchers have proposed current profiling based methods to minimize torque ripple, as proposed by some researchers in [1][2][3]16]. SRMs have been traditionally controlled by either openloop hysteresis or closed-loop pulse-width-modulation (PWM) current controllers.…”
