On applying parallel processing in advanced control of induction motor drives

Parallel processing offers realistic solutions to implement cost-effectively modern electrical drive systems comprising such advanced features as real-time control, online diagnostics and auto-tuning of system parameters. The implementation complexity of parallel processing by conventional multi-processor systems however has seldom been addressed and adequately documented. The proposed drive system serves to evaluate the impact of parallel processing on motor drive control applications, when effort can be turned away from low-level implementation as a result of emergence of some dedicated parallel processors. Some salient features of the drive system include real-time generation of pulse-width modulated (PWM) waveforms, programmable soft-starting, online user input for PWM parameters, dynamic braking and open loop vector control.<
