“…Absolute (14 bits per revolution) and incremental (with a resolution of 16384 pulses per revolution) encoders were used to measure position and angular speed, respectively. The speed measurement was performed using a technique based on a digital filter discussed in [28]. In this work, the PLL (Phase Locked Loop) method combined with the M method has been recommended.…”

The paper presents a method for designing a neural speed controller with use of Reinforcement Learning method. The controlled object is an electric drive with a synchronous motor with permanent magnets, having a complex mechanical structure and changeable parameters. Several research cases of the control system with a neural controller are presented, focusing on the change of object parameters. Also, the influence of the system critic behaviour is researched, where the critic is a function of control error and energy cost. It ensures long term performance stability without the need of switching off the adaptation algorithm. Numerous simulation tests were carried out and confirmed on a real stand.

This paper presents developed compact algorithms of space vector pulse width modulation (SVPWM) for six-switch and four-switch three-phase inverter. Calculations of the desired voltage vector in the PMSM drive are presented, an optimal voltage vector sequence and scaling factors for SVM has been derived to synthesize the reference voltage vector in each sampling period for healthy and fault drive. It has been proved by simulation and experimental results that four-switch inverter fed PMSM is able to operate steadily and with very good static and dynamic properties under the proposed SVPWM approach.
