Abstract: Speed control of hydro Turbine is an important issue and a shorter settling time is desired. In case of operation of drives with speed sensors, the performance of the drive is not satisfactory. To get satisfactory performance, a sensorless speed control system for hydro Turbine driving a synchronous generator in the hydroelectric power plants is developed. This work, we apply the approach of two methods of regulation: Super Twisting Control (STC) based on super-twisting observer (STO) and Super Twisting Control (STC) based on Higher Order Sliding Mode Observer (HOSMO). Simulation model in the presence of stochastic disturbance has been established in Matlab -Simulink. Simulation results demonstrate and validate the productiveness and performances of the proposed control method.
