Knowledge-based pulse width modulated embedded control and on-line condition monitoring of A.C. drives

There is no universally accepted control strategy or PWM generation method which could be used in the entire range of complex AC motor drive control applications. To attempt a solution for this problem, a novel general purpose knowledge-based control system is investigated. An investigation, using this concept, to provide clear regions in the spectrum of a PWM waveform in order to allow unhindered examination of signature components used in online condition monitoring diagnostics is presented. The development of hardware using Intel 8097 microcontrollers in a master-slave configuration and software modules adapting real-time concurrent programming techniques based on knowledge-based concepts is also presented
