摘要

The present research is indicating that the Permanent magnet motor drive couldudbecome serious competitor to the induction motor drive for servo application. Further, withudthe evolution of permanent magnet materials and control technology, the Permanent MagnetudSynchronous Motor (PMSM) has become a pronounced choice for low and mid powerudapplications such as computer peripheral equipments, robotics, adjustable speed drives andudelectric vehicles due to its special features like high power density, high torque/inertia ratio,udhigh operating efficiency, variable speed operation, reliability, and low cost etc. Here weuddeals with the detailed modeling of an IPMSM drive system with Hybrid PI-Fuzzy logicudcontroller (PI-FLC) as speed controller and Adaptive Hysteresis Current Controller as torqueudcontroller by controlling the current components of torque.In this thesis we deals with a simulation for speed control and improvement in theudperformance of a closed loop vector controlled IPMSM drive which employ two loops forudbetter speed tracking and fast dynamic response during transient as well as steady stateudconditions by controlling the torque component of current. The outer loop employ Hybrid PIFuzzyudlogic controller (PI-FLC) while inner loop as Adaptive Hysteresis Band CurrentudController (AHBCC) designed to reduce the torque ripple. Despite proportional plus Integralud(PI) controller are usually preferred as speed controller due to its fixed gain (Kp) and Integraludtime constant (Ki), the performance of PI controller are affected by parameters variations,udspeed change and load disturbances in PMSM, due to which it results to unsatisfied operationudunder transient conditions. The drawbacks of PI controller are minimized using fuzzy logicudcontroller (FLC). So for this a fuzzy control technique is also designed using mamdani type,udtriangular based 5x5 MFs and selecting the superior functionalities of PI and FLC, a HybridudPI-FLC designed for effective speed control under transient and steady state condition.The complete viability of above mentioned integrated control strategy is implementedudand tested in the MATLAB/Simulink environment and a performance comparison ofudproposed drive system with conventional PI, fuzzy logic controller and Hybrid PI-FuzzyudLogic Controller integrated separately as speed controller in terms of steady state andudtransient analysis with fixed step, variable step load and variable speed condition has beenudpresented. Beside this a detailed comparative study of AHBCC is also done withudConventional Hysteresis Current Control(CHCC) scheme. The simulation circuits parametersudfor IPMSM, inverter, speed and current controllers of the drive system are given inudAppendix-A.
