LQR Controller for Toroidal Continuously Variable Transmission in Reverse Motion

Identification of a toroidal continuously variable transmission using continuous-time system identification methods

“…The coefficients of determination R 2 were equal to 0.988 and 0.990 for the two output signals, the trunnion offset and the power roller tilting angle, respectively, during the experiments with the test-bed, while R 2 was equal to 0.990 for the gear ratio signal during the car experiment. Finally, the proposed model has been successfully used for the design of two controllers (Kawabe et al, 2002;Mensler, Kawabe, & Joe, 2003).…”
