...Mahdi Ahmadi This article is concerned with the assessment of nonlinearity in nonlinear dynamic systems to determine the feasibility of controlling a nonlinear system with either a single linear controller or a multimodel controller. The nonlinear system is decomposed into a bank of linear models...

... increase such that the accuracy of the numerical calculations may be negatively affected. Optimal time step for highest accuracy is always a challenge in numerical simulations. This is especially true when nonlinear dynamic systems, which are very sensitive to initial conditions and system parameters...
