Provided herein is a method and control system for a multiple-mode continuously variable transmission having a ball planetary variator. The control system has a transmission control module configured to receive a plurality of electronic input signals, and to determine a mode of operation from a plurality of control ranges based at least in part on the plurality of electronic input signals. The transmission control module includes a CVP control module. The CVP control module is adapted to implement a hydraulic pressure control process using fuzzy logic computations for operating in a micro slip speed region of the CVP. The fuzzy logic computations include determining weighting coefficients that are applied to minimum and maximum hydraulic pressure limits in the transmission.
