“…This hybrid nature of the system requires a special treatment to guarantee a better performance and to increase the accuracy in the description of the model. Therefore, over the past few years, different methods to synthesize controllers for hybrid systems have emerged in the continuous-time domain and in the discrete-time domain [4][5][6][7][8]. In the context of the techniques developed in the discrete-time domain, most of the approaches aim to satisfy two main requirements: (1) to yield a discrete-time model that accurately represents the dynamics of the continuous-time 2300 M. F. BRAGA ET AL.…”

“…In the present paper, a discretization method of continuous-time controllers based on frequency response matching such as the loop transfer function or a continuous-time controller is proposed. A number of frequency response based methods have already been proposed [1], [6], [8]- [11]. The methods proposed by Keller, et al [1], Anderson, et al [11], Mori, et al [9], Rafee, et al [5] and Cantoni, et al [12] are norm-based methods and the reference functions are closed-loop systems.…”

Norm-based methods sometimes provide high-order controllers if additional frequency dependent weighting functions are used in order to match the frequency response span over several decades.…”

“…Such a procedure is justified and well understood in the context of linear systems (see for example [1,2,10] and the references therein); however there is relatively little theoretical justification for this approximation in the context of nonlinear controllers and plants.…”
