Continuous Time-Varying Pure Feedback Control for Chained Nonholonomic Systems with Exponential Convergent Rate
نویسندگان
چکیده
In this paper, feedback stabilization problem of nonholonomic chained system is studied. A new continuous and time-varying design approach is proposed and it is a pure state feedback control. By injecting an exponential decaying disturbance scaled by the norm of the states, u1 drives the initial states away from the singular manifold {x|x1 = 0, ‖x‖ 6= 0} that causes singularity. In addition to the continuity, such a control has the exponential convergent rate that discontinuous control has. The enclosed simulation results verified the effectiveness of the proposed approach. Comparisons made with other existing continuous and discontinuous controls show that the proposed control has superior performance.

Smooth time-varying pure feedback control for chained non-holonomic systems with exponential convergent rate
The feedback stabilisation problem of non-holonomic chained systems and a novel feedback design scheme is proposed, which renders a smooth, time-varying, aperiodic, pure feedback control with exponential convergence rates. There are three main advantages with the proposed design. (i) In general, time-varying designs are mostly periodic and render asymptotic stability, whereas the proposed appro...

متن کاملControl Design for Systems in Chained Formwith Bounded Inputs
Discontinuous, time-invariant controllers have been recently proposed in the literature as an alternative method to stabilize nonholonomic systems. These control laws are not Lipschitz continuous at the origin and hence they may use signiicant amount of control eeort, especially if the initial conditions are close to an equilibrium manifold. We seek to remedy this situation by constructing boun...

It is known that the kinematic model of several nonholonomic systems can be converted into a chained form control system. Asymptotical stabilization of any equilibrium point of this system cannot be achieved by means of a continuous pure state feedback, but can be obtained by using a time-varying continuous feedback 20]. In the present paper, a backstepping technique is used to derive explicit ...
متن کاملStabilization of nonholonomic chained systems via nonregular feedback linearization
This paper addresses the problem of feedback stabilization of nonholonomic chained systems within the framework of nonregular feedback linearization. Firstly, the nonsmooth version of nonregular feedback linearization is formulated, and a criterion for nonregular feedback linearization is provided. Then, it is proved that a chained form is linearizable via nonregular feedback control, thus enab...
