| This paper presents the application of adaptive algorithm for the speed control of Switched Reluctance Motor (SRM) with load series DC machine. This system is feeding by Photovoltaic (PV) system. SRM is a highly nonlinear control plant and operates in saturation to maximize the torque output. A systematic approach to the modeling of highly nonlinear SRM drive system which includes the motor, converter, and its electronic controller is presented. Hysteresis current controlled mid-point converter is used to feed four phase, 8/6 pole SRM. Nonlinearity caused by magnetic saturation is accounted for accurate and real-time simulation of drive performance by considering experimental data of magnetization and static torque characteristics. Performance analysis of SRM drive is reported for a wide range of operating conditions via starting, reversal and load perturbation dynamics the performance indices of SRM drive system operating with adaptive controller for speed control and using the PI classical controller turn on angle for starting operation (dynamic operation). The results illustrate that the approach used are suitable for dynamic analysis and steady state of SRM fed from a PV system. It ensures smooth starting without initial hesitation and reduce the torque ripples. This proposed is explain the comparison between two technique for SRM (four phases) control system. First controller is adaptive speed control and the second controller is adaptive torque control. | ||
