초록
Hyperstability 이론에 의한 연속시간 시스템의 제어 알고리즘을 이산시간 선형시변 시스템의 적응제어에 직접 이용하여 시스템의 설계를 간단하게 하였다. 기준인력으로서 계단함수와 램프함수를 인가하여 설계된 시스템의 동작특성을 조사해 본 결과 공정의 출력이 모델의 출력에 적응함을 알 수 있었다.
A method is proposed for the adaptive control of linear time varying discrete systems. The stability problem of the model reference adaptive control systems is considered by means of the properties of hypergtability, The hyperstability approach also allows for solutions to the adaptation mechanism. Employing the principles of the continuous time case with output feedback renders it to the discrete case which simplified the system design. The system response is obtained by applying the ramp and step input as a reference signal to the system respectively. With checking the adaptation time for ramp and step input the validity of proposed algorithm was confirmed by the computer simulation.
