Kinematic and Dynamic Analyses of a Series-Type Independently Controllable Transmission Mechanism
An innovative transmission mechanism, referred to as a series-type independently controllable transmission (ICT), is proposed in this study. The series-type ICT is an alternative form of the parallel-type ICT proposed in the former researches. It can provide performing functions similar to those of an infinitely variable transmission (IVT) or a continuously variable transmission (CVT), and produce a required and desired angular output velocity that is independently manipulated by a controller and does not depend on the angular velocity of the input shaft. While being applied to variable speed wind power systems, the ICT mechanisms could overcome turbine speed fluctuations and provide a constant speed output to the generator to generate electricity with constant frequency. The series-type ICT is composed of two planetary gear trains and two transmission-connecting members. Kinematic and dynamic characteristics of the series-type ICT are investigated and analyzed, and their analytical equations are also derived for application.
