The problem of drive system velocity regulation with brushless dc motor was analyzed. Motor is supplied by the voltage inverter. For parametrical identification of the drive system mathematical model and selection of controller parameters, the Box’s numerical static optimization method was used. A subject of analysis was the sensitivity of control system structures to variations of motor parameter values.Laboratory tests were carried out in the system with 2 kW motor.
ANGULAR VELOCITY CONTROL OF A DRIVE SYSTEM WITH A BRUSHLESS PERMANENT MAGNET MOTOR
The problem of velocity regulation for a drive system with a brushless DC motor with an electronic commutator was analyzed. The motor was powered by a voltage inverter. The Box numerical static optimization method was used for the parametric identification of the drive’s mathematical model and for the selection of controller parameters. The sensitivity of control system structures to changes in motor parameter values was analyzed. Laboratory tests were carried out in a drive system with a 2 kW motor.
1. INTRODUCTION
So far, in electric drive systems, mainly two types of motors have been used, that is, the induction or direct-current classic ones. Nowadays, more and more commonly, the new generations of motors are used including motors with permanent magnets or synchronic reluctance motors. Slight power losses, small overall dimensions and lowering prices result in a situation when motors with permanent magnets are now competing with induction motors. (…)
