Uniformly-exact Second-order Sliding Mode Control
نویسنده
چکیده
The requirement of a uniformly bounded convergence time for all initial conditions is important for modern control theory. In particular the requirement appears in design of hybrid or switched systems. It can happen in such systems that a dynamic system repeatedly changes its configuration, and the configuration only lasts for some bounded time with its lower estimation known in advance. The natural requirement in that case is to get the desired system behavior before the next structural change takes place. Therefore, the exact regulation is to be achieved in uniformly bounded time irrespectively of the initial state at the time of the structural change. The corresponding transient convergence is called uniformly exact convergence (Angulo,Moreno,Fridman, 2011, 2012).

متن کاملA Novel Approach to Designing of Chattering-Free Sliding-Mode Control in Second-Order Discrete-Time Systems
In this paper, a chattering-free sliding-mode control is mainly proposed in a second-order discrete-time system. For achieving this purpose, firstly, a suitable control law would be derived by using the discrete-time Lyapunov stability theory and the sliding-mode concept. Then the input constraint is taken into account as a saturation function in the proposed control law. In order to guarantee ...
