This paper brings attention to the nonlinear dynamics of an induction motor's drive system with indirect field controlled. To understand the complex dynamics of system, some basic dynamical properties, such as equilibrium, stability are rigorously derived and studied. Chaotic attractors are first numerically verfied through investigating phase trajectories, bifurcation path, Poincare projections and dissipativity. Furthermore, a new sliding mode control method is proposed to gain the synchronization with different initial values. It can control the system to an equilibrium point. Numerical simulations are presented to demonstrate the effectiveness of the proposed controllers.
