Abstract

A linear sampled-data model for a current source inverter (CSI)-fed induction-motor vector control system which is controlled digitally by a microprocessor is derived. The system stability is discussed from the viewpoints of sampling period, microprocessor computation time, and feedback parameters by examining the loci of dominant eigenvalues of the state transition matrix and the transient responses. A comparison between the sampled-data model and a continuous system model is given.<>
