Theoretical and experimental investigation on an integral time-delay feedback control combined with a closed-loop control for an infinitely variable transmission system

A nonlinear closed-loop speed ratio control combined with an integral time-delay feedback is developed to adjust the of infinitely variable transmission (IVT) for a desired output any input speed. The IVT system based on its dynamic model, which involves forward controller and crank length varying operating conditions. can operate efficient driving performance optimal operation line prime mover. System identification carried out achieve high system. Comprehensive results experimental investigation are presented validate proposed strategy An instrumented rotation measurement designed so that quantities necessary be measured. Experimental show excellent tracking response constant This study reveals fluctuations reduced by control.
