Abstract: Partial variable stability is studied for a class of uncertain systems with uncertain equilibrium point. A stability model combining the ultimate boundedness and the asymptotic stability is proposed, and the conditions of the stability model are given. According to the proposed stability model, a damping assignment control scheme is presented, such that partial variable of the systems is stable in a given area and at the origin in different stages. The work of this paper develops the study on stability of uncertain systems, and solves the control problem of a class of uncertain systems with uncertain equilibrium point existing widely in industrial application. The effectiveness and the practicability of the research results are verified by the simulation experiment of a permanent magnet synchronous motor.
