A Synthesis Condition of Continuous Transfer Function for Monotonic Step Response : Hypothesis

단조 스텝응답을 주는 연속계 전달함수의 합성조건 : 가설

In this paper, a hypothesis in order that the impulse response of a stable linear system does not change sign is suggested. For fixed zeros of the systems, the problem of synthesizing such a system is reduced to the problem of finding a proper denominator polynomial so that the step response of the overall system will not overshoot. The hypothesis is associated with the generalized time constant by Kim[5]. Under the hypothesis, we propose several methods that allow to compose a continuous time LTI systems achieving non-negative impulse response.
