The principle of designing a multivariable linear optimal excitation controller by using the system zero-dynamic method is expounded. Practical algorithms implemented on a microcomputer excitation regulator are presented. Various dynamic and static stability tests on the simulated generator set show that this The controller can greatly improve the damping ability of the generator to suppress the oscillation and improve the static and transient stability than the PID controller
