Abstract
This paper depicts an experimental validation and simulation for speed control under load and no load conditions. It delineates the detail study of a closed loop vector controlled permanent magnet synchronous motor drive. This system consists of two loops for smooth speed tracking as well as reduced torque undulation. PMSM drives facilitate better dynamic responses during both steady state and dynamic conditions by monitoring the component of torque current. The resistive loads are varied and resultant speed and torque are studied. Experimental work has been performed on PMSM drives under different conditions and results are compared with conventional PI and Fuzzy logic controller. Â
Highlights
From literature survey, it was construed that the permanent magnet synchronous motor drives with special features will be able to meet different requirement for instance better dynamic response, elevated power factor and broad operating speed range as compared to conventional AC machine drives
Fuzzy logic based speed controller of an interior permanent magnet synchronous motor (PMSM) drives were studied under different dynamic conditions and it was demonstrated that better performance can be achieved by increasing the number of rules [4]
Ripple torque was found to be augmented in case of hybrid- fuzzy PI controller [6], but vector control based PMSM drive using hybrid PI-fuzzy logic controller depicted fast dynamic response and reduce torque ripples [7]
Summary
It was construed that the permanent magnet synchronous motor drives with special features will be able to meet different requirement for instance better dynamic response, elevated power factor and broad operating speed range as compared to conventional AC machine drives. Due to non-existence of different mechanical components likes brushes and slip rings makes the motor lighter, high aspect ratio, which improves efficiency and reliability. It was found from literature [1] that when rotor speed was increased, the response was found to be slightly under damp. Fuzzy logic based speed controller of an interior PMSM drives were studied under different dynamic conditions and it was demonstrated that better performance can be achieved by increasing the number of rules [4]. This paper mainly studies about PI and Fuzzy PI controller and fuzzy rules based which are used to calculate the response Both PI and Fuzzy PI control technique was carried out for FPGA based permanent magnet synchronous motor drive. The detailed responses were demonstrated under no-load, load and sudden change in speed conditions
