Optimal Fuzzy Control System Design for Steam Power Plant: Local Concept Approach
نویسنده
چکیده
This paper addresses the design of a fuzzy control system with a fuzzy controller and a fuzzy estimator for a fossil fuelled drum boiler-turbine-generator unit on the basis of a dynamic fuzzy model that was developed in our recently published paper. In the design procedure, a dynamics augmentation is introduced and a dynamic fuzzy augmented system is then determined for the nonlinear boiler-turbine system to deal with its nonminimum phase behaviour. The fuzzy control system is designed from a local concept viewpoint on the basis of the optimal control theory. The good performance of the designed fuzzy control system is shown by simulations in various conditions.

ABSTRACT: This paper focuses on design of nonlinear power plant controller using immune based multiobjective fuzzy approach. The thermal power plant is typically regulated by the fuel flow rate, the spray flow rate, and the gas recirculation flow rate. However, Strictly maintaining the steam temperature can be difficult due to heating value variation to the fuel source, time delay changes in th...
متن کاملPower Plant Boiler Level Control Using Immune Algorithm Based Fuzzy Rule Auto-tuning
The key study problem of level control of boiler (or steam generator) in power plants exists because they are typically non-linear and multi-variable with multiple control objectives. The conventional controls such as PID compensators do not have the flexibility necessary to provide a good performance over a wide region of operation in this system. Since application of modern optimal control te...
