A model free terminal sliding mode controller has been proposed. The proposed controller is data driven i.e. based only on input and output data (thus, model free). This method employs a recursive nonlinear sliding surface. This leads to higher tracking precision and to finite time convergence of the response. The method uses “Model Free Adaptive Controller” approach, combined with “Discrete time Sliding Mode Controller” method. Boundedness of tracking error is proved analytically. Theoretical analysis also shows the superiority of the proposed method over Model Free Linear Sliding Mode Controller. Analysis results are confirmed via simulation
