Abstract :
This paper presents a new necessary and sufficient condition for controllability of nonlinear systems. Over the differential field of the nonlinear system, a polynomial equation is derived to present the system behavior. The condition for controllability is then presented in terms of the common factor of the polynomial equation. This condition extends the well known result for linear system controllability to nonlinear systems, and provides an effective procedure for examining controllability of nonlinear systems
