Abstract

The permanent magnet step motor ( PM-step motor) is one of the mast important control elements used in process control industry. In this study a method is proposed by the use of the sensitivities of the transfer function to determine the optimum parameter tolerances These tolerances keep the deviation of the output of the PM-step motor due to parameter variations, in tolerance region. Furthermore a sensitivity measure is defined to be used to improve the sensitivity performance of a PM-step motor and Co compare various PM-step motors with different set of design parameter values which realize the same transfer function.
