Real-time transputer-based measurement apparatus: performance testing

The paper deals with transputer-based equipment used in on-line indirect measurement on induction motors, by using an estimation algorithm, performed in real time. Starting with a brief description of the actual equipment, some considerations relating to the multiprocessor architecture are reported, in order to point out hardware and software solutions adopted to fit real-time requirements. The dynamic behavior of the measurement station is inspected, in order to highlight the overall equipment performance in terms of the achievable accuracy and execution speed. The paper is concluded with some experimental results, concerning the working operations of an actual induction motor fed by an inverter
