Adaptive Critic Design Based Neurocontrollers for Turbogenerator Control

Nonlinear non-stationary large scale (NNLS) systems such as power system networks, telecommunication networks, financial and transportation systems are difficult to control and manage. Mathematical models of such systems are typically derived based on linear techniques, and wide margins of safety are allowed in order to ensure stable operation. In the era of a deregulated electricity industry, and an emphasis on competitive pricing, it will become necessary to reduce these safety margins as much as possible while still maintaining reliable service. Advanced intelligent identification and control schemes are therefore required in order to maximize the throughput/performance of such systems by reducing the otherwise wide safety margins. Neurocontrollers offer such a possibility.
