Input-output linearization of retarded nonlinear systems by an extended Lie derivative

Abstract: This paper considers the input-output linearization problem for retarded nonlinear systems which have time-delays in the state. By using an extension of the Lie derivative for functional differential equations, we derive a coordinates transformation and a state feedback to obtain linear inputoutput behavior for a class of retarded nonlinear systems. We also examine the stability condition of the total systems. The effectiveness of the proposed technique is demonstrated through numerical simulations. 1364 0-780… Show more

“…If k(φ) ∈ U for all φ ∈ C (i.e., the saturation constraints are fulfilled by the continuous time control law), and (4.1) holds (globally), then global stabilization in the sampleand-hold sense is achieved, according to Theorem 5.3. The following corollary shows how Theorem 5.5 can be applied to the particular class of nonlinear retarded systems which are input-output feedback linearizable and stabilizable by (continuous time) state feedback (see [57,Theorem 3.3], [15], [16], [44]). …”

“…The map Ψ describes the change of coordinates by which the control law (6.12) is found and, by the control law (6.12), the following ODE dψ(x(t)) dt = Hψ(x(t)), t ≥ 0, holds (see [16], [44], [15]). The functional V is a CLKF, in C S , for the system described by (6.11), according to Definition 4.1.…”

“…This is based on the possibility of defining, locally (around a convenient state) and starting from a sufficiently smooth output, a suitable coordinate transformation permitting an equivalent linear representation of a subsystem (and maybe the overall system) in the new coordinates. This approach is widely studied in the case of delay-free (see, e.g., [4,12,17], and references therein) and constant-delay control systems (see, e.g., [2,5,8,9,11,14,15,21], see also the more recent paper [1], where, motivated by some observability problems of nonlinear constant-delay systems, necessary and sufficient conditions allowing an equivalent linear weakly observable time-delay system representation have been presented.…”
