A Green Innovative Sports Bike Based on an Induction Generator with a Nonlinear Controller

This paper addresses the problem of designing a non-linear control of a stationary bicyle and mechanical energy conversion system with an induction generator. The considered system consists of a squirrel cage induction generator (SIG) connected with an AC/DC and DC/DC PWM converters. There are three main control objectives: (i) torque regulation based on the torque control applied by the athlete; (ii) rotor flux reference tracking; (iii) well regulated DC-link voltage. After a complete system model, the backstepping approach is used to design a non-linear controller. To describe the performance of the control system, a formal analysis based on Lyapunov stability is carried out. Several simulations show that all control objectives are achieved, and the performances has resilient properties.
