Abstract : We are introducing a model-free control and a control with a restricted model for finite-dimensional complex systems. This control design may be viewed as a contribution to "intelligent'' PID controllers, the tuning of which becomes quite straightforward, even with highly nonlinear and/or time-varying systems. Our main tool is a newly developed numerical differentiation. Differential algebra provides the theoretical framework. Our approach is validated by several numerical experiments.
Keywords : differential algebra linear systems nonlinear systems model-free control control with a restricted model predictive control delay systems PID intelligent PID controllers universal control robustness diagnosis large-scale systems anti-windup numerical differentiators frictions non-minimum phase systems differential algebra.
