Optimal control of a micro-alternator system

This paper describes a laboratory model of a turbogenerator and associated computer system for on-line closed loop control. This has been used to investigate the performauce of the generator with a linear optimal controller, which provides integrated control of governor and excitation systems. Results are presented for both steady-state and transient operating conditions, and these illustrate the potential of such controllers when used in conjunction with thyristor exciters, electro-hydraulic governors, and fast turbine valving.
