Model Reference Adaptive Control Based PID Controller Designs for Steam Turbine Speed

Sherin A Kochummen | Nasar A ^[5]

Abstract: A steam turbine, key part of the power plant that allows the conversion of the heat energy to electricity via mechanical energy. Steam turbine control systems are being designed with todays technology to operate a turbine in a safe and reliable manner. Tandem compound reheat steam turbine is introduced to increase the thermodynamic efficiency by multistage steam expansion. Adaptation of PID controller using certain adaptation techniques improves the performance of the system. This paper investigates Model Reference Adaptive Controller for speed control of Tandem compound reheat steam turbine using MIT Rule and Lyapunov rule to bring up quick tracking and steady state control over the turbine speed thus comparing the result with conventional PID controller.
