چکیده

A steam turbine, heart of all refineries. This work presents the mathematical modelling of the steam turbine unit in isolated operating condition, based on the continuity equation including servomotor for actuation purpose. Steam turbine should run at a constant speed for its safe operation and frequency stability. Adaptation of different controller like Feedback, PI, PID 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 Lyapunov Rule to improve set point tracking and control over the turbine speed.

Robust Control of Encoderless Synchronous Reluctance Motor Drives Based on Adaptive Backstepping and Input-Output Feedback Linearization Techniques

In this paper, the design and implementation of adaptive speed controller for a sensorless synchronous reluctance motor (SynRM) drive system is proposed. A combination of well-known adaptive input-output feedback linearization (AIOFL) and adaptive backstepping (ABS) techniques are used for speed tracking control of SynRM. The AIOFL controller is capable of estimating motor two-axis inductances ...
