On the right-inversion of partially minimum-phase systems: case study

This technical manuscript reports the detailed calculations, and simulations carried on the case study of the 4-tanks system based on the control procedure proposed in [2]. The case study illustrates how, starting from a nonminimum phase nonlinear system with a linear output, one goes about identifying the minimum phase zeros of the LTM model of the system, calculating a related dummy output, with respect to which the original nonlinear system is minimum phase. Regulation of the original output is thus possible using standard static feedback controls. KEYWORDS Contents
