| Abstract | Redesign and stability analysis of I/O VS-MRAC systems are presented. The key novel idea is to formulate the effect of the uncertainty on the plant "high-frequency gain" (HFG) as an input disturbance acting on a plant with known (nominal) HFG. This leads to redesign and substantial simplification of the stability analysis, under less restrictive assumptions. Detailed discussion is presented for the case of relative degree n = 2. The paper briefly indicates how the analysis can be extended (more easily) to the general case n 2. 1 Introduction A solution to the problem of designing variable structure (VS) control systems using only I/O measurements was recently proposed by [14], for the case of plants with relative degree n = 1, and by [11], for the general case n 1. The structure of the controller was inspired from that of the standard parameter adaptive (PA) MRAC [19] and will thus be referred to as the "I/O VS-MRAC" henceforth. The I/O VS-MRAC was verified to exhibit r... |
