Abstract :
The paper compares operation of a high performance drive with PI and fuzzy logic (FL) speed control. Two initial designs of speed controllers are considered and it is emphasised that any attempt to provide a fair comparison must aim at achieving the same response with both controllers for the design case. Next, it is shown how a selective approach to choice of transients that are used to underpin certain desirable conclusion (usually superiority of FL control) can be misleading. Detailed comparison of performance over the entire speed range for two initial designs shows that, in general, there are speed regions where PI control provides better response, as well as regions where FL and PI control yield more or less the same response
