In this paper sensor less control of SRM Drives is presented. A fuzzy PID controller is used and the fundamentals of the controller are illustrated. Sensor less operation is achieved through a binary observer based algorithm. In order to avoid using the look up tables of motor characteristics, which makes the system depends on motor parameters, an adaptive identification algorithm is used to estimate the nonlinear motor parameters. This method makes position and speed estimation more accurate and robust towards any model uncertainty, also it is a suitable replacement for a priori knowledge of the motor characteristics.
