“…Digital implementation is usually desired for achieving better reliability, lower cost, smaller size, increased flexibility and better performance. Digital redesign techniques are able to retain the physical insight of continuoustime design and maintain the essential system performance from their analogue counterparts (Kuo 1980;Sunkel, Shieh, and Zhang 1991;Rafee, Chen, and Malik 1997;Shieh, Wang, and Panicker 1998;Fujimoto, Kawamura, and Tomizuka 1999;Guo, Shieh, Chen, and Lin 2000). In this work, predictionbased digital redesign (Guo et al 2000), a technique that has been successfully employed to control the highly nonlinear chaotic systems, is used to convert the designed analogue controller into an equivalent digital controller.…”
