Gain-scheduled Non-linear Servo Controller for Toroidal Continuously Variable Transmission

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

Application of Multi-objective Optimization for Optimization of Half-toroidal Continuously Variable Transmission

Among different goals defined in vehicle design process, fuel consumption (FC) is one of the most important objectives, which significantly has taken into account lately, both by the customers and vehicle manufacturers. One of the significant parameters which impacts the vehicle FC is the efficiency of vehicle's power train. In this paper, a half-toroidal continuously variable transmission (CVT...

an experimental study on full toroidal continuously variable transmission system

abstract: a continuously variable transmission (cvt) is a transmission which may change step less by way of an infinite variety of effective gear ratios between maximum and minimum values. this contrasts with different mechanical transmissions that solely permit just a few different distinct gear ratios to be selected. continuously variable transmissions (cvts) are mechanical devices that allow...

Modelling and Optimization of Toroidal Continuously Variable Transmission in ECE Driving Cycle

In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...

Robust gain-scheduled controller for linear parameter varying systems

Proportional-integral-derivative (PID) controller is the most widely used in industry due to its simplicity and performance characteristics. However, a number of processes with time-variant or nonlinear characteristics are difficult to be handled with a conventional PID controller. To address this problem, an enhanced PID controller exhibiting improved performance than the conventional linear f...
