Abstract

The current work aims to simulate the operation of the electric motor in one of the most important industrial applications, which is printers, by adopting stepper motors (SM). The performance of the motor is also improved by adopting traditional control systems and adjusting them using the gray wolf optimization (GWO) advanced algorithm. It works to adjust the parameters of a conventional controller. Simulation to reach an appropriate design with high performance, which is obtained by adopting the integral time absolute error (ITAE) function to get rid of the error for transient cases. Transfer function was adopted to represent the engine and two methods of control were used, traditional and advanced optimization. Results demonstrated the possibility of improving performance by adopting both methods with a clear superiority of advanced optimization. Response of SM without controller for close loop shows the values of each rising time equal 130.440 ms, overshoot equal 0.505%, and undershoot equal 1.077%. Response of SM for close loop with proportional-integral-derivative controllers (PIDC) shows the parameters, performance, and robustness of PIDC also the values of overshoot=9.16%, settling time=0.406, and rise time=0.0628 s. Results were developed by using GWO-PID over the previous cases by reducing values of overshoot to zero, rise time, and settling time to 0.00145 and 0.0027 respectively.

Abstract

Torque ripple is a significant undesirable aspect of permanent magnet (PM) machine. It is mainly contributed by cogging torque, which is inherit feature of the PM machine. Interior permanent magnet (IPM) motor with a sinusoidal + third-order harmonic injected rotor pole shape has been introduced as one of the most efficient rotor pole arc iron shape techniques to minimize the cogging torque. Such method showed a reduction in the cogging torque compared to the traditional designs. Generally, imperfections in the manufacturing process can exacerbate cogging torque and, by extension, torque ripple. This research assesses how manufacturing tolerances influence the torque ripple of the IPM motor having sinusoidal + third order harmonic rotor pole shape. The investigation has been carried out using two-dimension finite element analysis(2D-FEA) method, ANSOFT MAXWELL program. Different models of the IPMs with sinusoidal + third order harmonic rotor pole shape have been made to simulate healthy, eccentricity and PM diversity cases. According to the simulation results, it has been found that PM diversity leads to introduce additional harmonics in the cogging torque waveforms, i.e., in addition to the fundamental harmonic, which is the 60th harmonic orders, the 12th harmonic and its multiples harmonic orders were presented, consequently resulting in increasing the torque ripple. Moreover, the obtained results have shown that the static eccentricity has more negative effect on the torque ripple compared to the dynamic counterpart, i.e. the torque ripple of the static eccentricity is about 20% higher than that of the dynamic counterpart.
