WebProblem Find the Lyapunov function “Linearization methods and control of nonlinear systems” Monash University, Australia Carleman Linearization – Lyapunov Stability … WebTraditional methods for treating nonlinearity are often limited in validity or specific to the problem. The standard point-wise linearization based on Taylor expansion, for example, is valid only in the vicinity of the original nonlinear system. The Lyapunov method is a general theory, but a specific Lyapunov screen mirror on samsungWebequilibrium point can be determined by linearization about that point. In Section 6, we extend Lyapunov’s method to non-autonomous systems. We define the concepts of uniform stability, uniform asymptotic stability, and exponential stability of the equilibrium point of a non-autonomous system and give Lyapunov’s method for testing them. screen mirror on windows
