Abstract

In this paper, a data-based output feedback control method is developed for a class of nonlinear affine systems. This method requires little prior knowledge about the system. It does not need to know or to build the mathematical model of the system. We introduce a fast sampling technique to measure the output signal, which contains information about the plant. The zero-order hold (ZOH) and the control switching techniques are also applied for information collection. Then, the feedback gain matrix is calculated and adjusted according to these sampled data. Computer simulation results demonstrate the feasibility of this data-based control method.
