“…However, for rotary SRA it is limited. Most of these early works used model-based control, which improves performance but depends on system modelling accuracy and quality [14]- [18]. Classical control uses the proportional integral derivative (PID) because of its simple design and high applicability for industrial operations.…”

Over the last decade, industrial applications and promising research domains including robotics and automotive engineering have adopted the rotary switched reluctance actuator (SRA). SRA's fault tolerance, simple, strong structure, and high-frequency operation make it popular. However, the SRA's nonlinear magnetic flux flow and saturation operation negate its benefits. Several control systems have been developed; however, they often need extensive mechanism models and advanced control theory, making them impracticable. This paper proposes a modified proportional integral derivative (PID) controller to evaluate the control performance, which comprises of PID controller with an anti-windup, a linearizer unit, and switching mechanism to activate the SRA phases. The linearizer unit aids to compensate for the nonlinear current-displacement relationship. The anti-windup element helps to halt the integral action during the starting motion. At the fully aligned position, 60°, the modified PID reduced positioning steady-state error by 4.3 times at 76.9%, overshoot by 48.8%, and settling time by 25.3%. Both the modified PID and conventional PID showed zero steady-state error at intermediate position, 70°, however the modified PID controller depicted an improved percentage overshoot by 54.5% and settling time by 74.5%. The results show that the modified PID outperforms conventional PID in transient response, steady-state error, overshoot, and settling time.

“…Study [20] used an RBF neural network and a BP neural network for SRM model identification and speed control, respectively, proposing a neural network PID control strategy with strong adaptive ability and adjustable parameters. The speed regulation system built with a robust governor in study [21] effectively reduced the overshoot, rise time, and setting time of the system and achieved a faster response speed and a stronger robustness of the SRM. Reference [22] uses a genetic algorithm to determine the optimal PID control parameters of linear switched reluctance motors to optimize their control speed.…”

Deflection switched reluctance motors (DSRM) are prone to chattering at low speeds, which always affects the output efficiency of the DSRM and the mechanical loss of the motor. Combining the characteristics of a traditional reluctance motor with the strong nonlinear and high coupling of the DSRM, a control system for a DSRM based on a flexible neural network (FNN) is proposed in this paper. Based on the better robustness and fault tolerance of fuzzy PI control, the given speed signal is adjusted and converted into a torque control signal. As a result, the FNN control module possesses the strong self-learning ability and adaptive adjustment ability necessary to obtain the control voltage signal. Through simulations and experiments, it was verified that the control system can run stably on DSRM and shows good dynamic performance and anti-interference ability.

Fallas de cortocircuitoEl diagnóstico de fallas incipientes en las máquinas eléctricas es una de las tareas más complejas al momento de vigilar su desempeño, se tiene gran interés en desarrollar modelos que representen el comportamiento del aislante.La fase inicial de la mayoría de fallas incipientes es por medio del deterioro del aislante y puntos de calor generados por estrés eléctrico; esto permite que el dieléctrico no aislé las espiras de los devanados.…”

In this work, the analysis of the inter-turn short-circuit fault of the incipient type was carried out for an 8/6-pole Variable Reluctance Motor (MRV) using the numerical co-simulation technique a finite element model is used for the motor, a PI type speed controller is implemented and the asymmetric H half bridge converter is also modeled considering the associated power electronics. A description of the machine is presented including the principle of operation, obtaining the commutation sequence and finally a magnetodynamic analysis using the finite element model is performed. Subsequently, a controller of the PI form with rejection of high frequency disturbances is proposed in order to evaluate it in regulation and speed tracking problems without fault. Finally a inter-turn short.circuit fault is simulated at phase A (1, 3, 5 and 7 turns). The fault was represented by means of an RC circuit in parallel with the section of the winding that is short-circuited in one phase of the motor, capturing the behavior of the electromagnetic torque, current and voltage of each phase and angular velocity of the rotor.
