Nonholonomic system - In physics and mathematics, a nonholonomic system is a system in which a return to the original internal configuration does not guarantee return to the original system position. In other words, unlike with a holonomic system, the outcome of a nonholonomic system is path -dependent, and the the number of generalized coordinates required to represent a system completely is more than its control degrees of freedom(sometimes called differential degrees of freedom,DDOF).
