Abstract: In th is paper we fist analyze the stability of ro to r speed estimation and ro to r observation w ith adap tive flux observer in the speed senso r2less contro l of induction mo to rs. A fter that, based on the model refer2 ence adap tive system s we p ropo se a new estimating algo rithm of ro to r speed. W ith th is algo rithm the system is stable fo r any operation states. Simulation results show that new algo rithm is efficient.
