Abstract: |
The traditional deadbeat control is of mathematical model control method,the control property of which is greatly influenced by the system parameters. An improved deadbeat control stra-tegy is presented,in which the on-line identification parameter method is used and the controller parameters are real-time corrected. As a result,the controller is adaptable to system parameter chan-ges and its tracing property is effectively improved. |
