System time-varying controller design via E.A. method

The new concepts of time-varying stabilizer via dynamic pole assignment and eigenstructure assignment method (E.A. method) are introduced in this paper. The theorem of dynamic pole assignment is obtained by employing the piecewise constant concept. By specifying the final eigenstructure, the parameters of the time-varying stabilizer can be determined via output controller is evaluated, and examples of a one-machine infinite-bus system and a multimachine system in power system, are given to illustrate the advantages and effectiveness of the proposed technique.
