In this paper, a new control scheme named model-free adaptive control with contractive constraints (MFAC-CC) is proposed based on compact form dynamic linearization (CFDL) for a class of nonlinear systems. In this strategy, contractive constraints are added into the model-free adaptive control (MFAC) algorithm, which lead to the tracking error decaying gradually. A numerical comparison experiment...
The actual industrial systems are usually high order system with long time delay. These characteristics will bring a lot of troubles in building the models. Sometimes we need to know the pure delay of the system when designing the controller and at the same time we hope the model has low order. The traditional methods like unit step response and pade approximation to estimate time delay have some...
