Abstract

Three different differential equation resolution methods are studied in a real-time microprocessor-based vector control algorithm for an AC motor drive. Both accuracy and computing speed are analysed in these methods. Simulation and experimental results with an Intel 80486 32-bit microprocessor running at 50 MHz are included in this paper. The sophisticated resolution methods show similar accuracy and larger processing times when compared to traditional methods. The length of the variables (single or double) is an important parameter for the performance of the system and the stability of the numerical algorithms
