Optimization and simulation of traction drive of continuously variable transmission

According to the force of traction type variator transfer function,establishes the equation of state,then carries on the optimization using the optimum control theory to the transmission ratio servocontrol.Drawing the logarithmic frequency characteristics of the open-loop system,tests the dynamic quality of system,simulates the optimized control system by the MATLAB/Simulink software,analyzes the simulated results.The simulation shows that the optimal dynamic performance of the system has improved obviously.
