| Abstract: | This paper, combined adaptive control theory with optimal control theory, presents an adaptive optimal excitation control ( AOEC ) due to the defects of linear optimal control ( LOEC ) . The controller is composed of three parts, multi-variable parameters identification optimal feedback parameters calculation and control algorithm operation. The results obtained from digital simulation show that the new AOEC could automatically follow the system operation status, identificate the system parameters varying constantly on line, and make the control optimal. Therefore it improves the dynamic characteristic, and increases the system transient stability. |
