In this paper, a model based control algorithm for pressure control type CVT has been developed. Model based controller was designed based on Kpsi map and steady state primary pressure model for a ratio control valve. It was found from the experiments thai the model based controller has similar tracking performance compared with the PID controller. However, model based controller showed superior robustness to the PID controller especially for the overdrive range. It is expected that the model based controller can be used to prevent the belt slippage and improve the shift speed.<br/>
