Nettet30. aug. 2024 · How do you linearize a nonlinear system? Linearization is a linear approximation of a nonlinear system that is valid in a small region around an operating point. For example, suppose that the nonlinear function is y = x 2 . Linearizing this nonlinear function about the operating point x = 1, y = 1 results in a linear function y = … NettetThe goal is to take the nonlinear system ˙z = g(z, u) and linearize it to ˙z = Ax + Bu. To do this we must compute the Jacobian matrices A: = ∂g ( z, u) ∂z ∈ R3 × 3 and B: = ∂g ( z, u) ∂u ∈ R3 × 2. After computing A, it was easy to determine that linearization would fail about any equilibrium point (none exist!), so I didn't ...
