For a class of unknown non-uniformly sampled discrete time nonlinear non-affine systems
the corresponding model free adaptive controller is designed by using equivalent data model in the current working point and the non-linear estimation of pseudo Jacobi matrix (PJM) by using input and output data. The proposed control method has the following characteristics:the designed controller requires only the non-uniformly sampled input and output data
and does not contain any information of the system model. The control algorithm has small calculation amount
and is easy to achieve. Finally
the effectiveness of the proposed method is verified by the simulation results of a non-uniformly sampled discrete-time nonlinear system.
