An automated approach to deriving analytical expressions for the speed–torque character istics for an arbitrary impulse control method for the power amplifier–servomotor electric drive sys tem is developed. Mathematical expressions for the speed–torque characteristics for impulse modes and commutation methods are obtained based on the suggested approach, and an interactive applica tion is developed. This application makes it possible to represent the family of speed–torque charac teristics for the corresponding control method and impulse mode and study voltage and current wave form diagrams at an arbitrary point of the speed–torque characteristics for the given motor parameters and pulsewidth modulation period. Automation of the procedure of deriving analytical expressions and the development of the interactive application were carried out using the Mathematica system.
