| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 90 === A numerical process based technique for control system synthesis is proposed. The method is applicable when the system is open-loop stable. The major features of this method are two folds.
First,a correlation equation is established between the open-loop system response and the desired closed-loop system model parameters. As the result, it is possible to synththesize the controllers from a batch of plant test data without the explicit knowledge of a parametrized plant model. Second, the workability of the synthesized controller may be verified in due process.
But, If we must be sampled from open-loop tests that are performed under a relaxed initial condition, a limitation that may be inconvenient in some applications A modified design method of DBCS to remove this limitation is proposed. The major purpose of this research is to design controllers under the nonrelaxed initial condition with modified DBCS.
