A new intelligent adaptive mechanism for sensorless control of permanent magnet synchronous motor drive

This paper presents an intelligent adaptive mechanism for sensorless permanent magnet synchronous motor drive. The mammalian brain inspired intelligent controller named as brain emotional controller is introduced in adaptive mechanism of model reference adaptive system to estimate rotor speed, rotor position and for motor parameters identification. The brain emotional controller design includes certain parts of limbic system of mammalian brain. The brain emotion based adaptive mechanism is constructed with state tracking error of reference and adjustable models using Lyapunov function. Moreover, to control the speed of drive the brain emotional control based speed regulator is designed to achieve improved performance. The effectiveness of adaptive mechanism is verified using simulations and results obtained are analyzed by real time implementation using hardware-in-loop set up. The performance of proposed strategy is validated by operating at different operating and loading conditions. The results show the effectiveness and robustness of proposed brain emotional control strategy.
