Abstract

This thesis’s main goal is to employ modern intelligent methodologies such as fuzzy logic controllers (FLC) and metaheuristic algorithms (MHA) to improve the performance of field-oriented-control (FOC) of the permanent magnet synchronous motor (PMSM). First, PMSM mathematical model was described in details along with the foundational parts of FOC such as feed forward compensation (FFC) decoupling technique. Then, a set of proportional-integral (PI) controllers optimized using classical tuning techniques (CT) were presented and compared to a set of PI controllers tuned by a new hybrid metaheuristic algorithm known as symbiotic-particle-sewing (SPS). In this comparison, both sets of controllers were used for FOC of PMSM, and upon analysis of this comparison results, SPS based PI (SPS-PI) proved to be far better than CT based PI (CT-PI). However, SPS-PI performance was still considered unsatisfactory due to its unprecise transient response, and high steady state error (SSE) when a load charge is applied. Further, to address the downsides of SPS-PI, an interval Type-1 FLC with tuned membership functions (MFS) denoted by (F1MF) was designed and optimized using SPS algorithm for speed control of PMSM with the currents remaining controlled by SPS-PI, and then compared to CT-PI and SPS based conventional FLC with unoptimized MFS denoted by (FC1). Furthermore, F1MF enhanced tolerance to load charges and unmatched transient response proved its superiority over FC1 and CT-PI controllers. However, although F1MF’s settling time (ST) and overshoot (OS) rejection were very acceptable, its overall SSE minimization performance fell short when high load charges were applied. Therefore, an interval Type-2 based FLC (FLC2) with tuned MFS denoted by (F2MF), was presented and tuned using SPS algorithm. F2MF outmatched F1MF SSE minimization in the presence of high load charges but at the cost of a significant downgrade in its transient response ST and OS rejection compared to F1MF. Additionally, in order to address F2MF transient response problems while maintaining its high disturbances tolerance, it was paired with a fractional derivative (FD) and an adaptive low pass filter (ALF) combination denoted by (ALD). Finally, through MATLAB/SIMULINK and processor in the loop (PIL) co-simulation. The new controller constructed of F2MF and ALD (F2MF-ALD) was proven to be functional and far superior to its simpler variants such as F1MF, and F2MF when used for speed control of PMSM.
