Nonlinear control of a Continuously Variable Transmission (CVT)
IEEE Transactions on Control Systems Technology, 2003Co-Authors: Pradeep Setlur, J. R. Wagner, D.m. Dawson, Barbra SamuelsAbstract:Automotive engineers are Continuously exploring various engine, Transmission, and chassis technologies to increase overall vehicle performance, fuel economy, and safety. One promising powertrain concept is the Continuously Variable Transmission (CVT), which offers a continuum of infinitely Variable gear ratios between established minimum and maximum limits. This continuous gear ratio spectrum can increase the overall powertrain efficiency and eliminate the unwanted jerks associated with manual and automatic Transmissions. Although basic CVT designs may have difficulty with high torque/low speed requirements, a power split Continuously Variable Transmission configuration offers both fixed gearing and adjustable pulleys to satisfy driving demands. The effective control of the Variable radius pulleys allows the designation of engine torque/speed to improve overall system performance for a given operating condition. In this paper, the fundamental components, configuration, and kinematics of a power split CVT will be briefly introduced. The problem of wheel speed (i.e., cruise) control of a CVT equipped vehicle will be considered. An innovative adaptive nonlinear controller will be designed to ensure asymptotic tracking of the desired wheel speed. Representative numerical results are presented and discussed to demonstrate the ability of the integrated CVT and engine controller in tracking the prescribed wheel speed.

design of an electrical Continuously Variable Transmission based wind energy conversion system
IEEE Transactions on Industrial Electronics, 2016Co-Authors: Yulong Liu, Shuangxia Niu, W N FuAbstract:The electrical Continuously Variable Transmission system is a very promising concept for Variable-speed constant-frequency wind power generation due to its ability of seamless speed adjustment. In this paper, a novel wind energy conversion system based on electrical Continuously Variable Transmission is proposed. This system combines the merits of two popular wind generation concepts: It enjoys high torque density like the permanent-magnet synchronous generator system and, also, it needs only a partial-scale converter like a doubly fed induction generator system. With a special doubly fed dual rotor structure, the system realizes both speed variation and power generation within one single machine, which makes it very compact. Besides introducing its structure and working principle, the design and performance analysis of the machine are presented in this paper. A prototype is made and tested for validation.

Novel electrical Continuously Variable Transmission system and its numerical model
IEEE Transactions on Magnetics, 2014Co-Authors: Yulong Liu, S.l. Ho, W N FuAbstract:A novel electrical Continuously Variable Transmission (E-CVT) system for hybrid electric vehicles is presented. The merits of the system, which is comprised of a magnetic gear (MG) integrated permanent magnet brushless machine, are its compactness, light weight, very high torque density, and simple structure. The integrated MG is ingeniously used to greatly amplify its output torque. It serves the functions of both power splitting and coupling. The drawbacks of mechanical gears or brushes in traditional systems are overcome. A design method based on finite element method for maximizing the torque output of the machine is presented and the performance of the machine in the E-CVT system is validated.
