Novel Switching H2/H∞ Control: Combination of Dwell Time Switching Signal and Multiple Lyapunov Function
نویسندگان
چکیده
In this paper, a switching strategy is employed to solve the H2/H∞ multi objective controller design. Two controllers are designed to meet the H2 and H∞ performance specifications. Linear matrix inequalities are used in the controller design process. New switching signal is defined which is the combination of dwell time switching signal and multiple Lyapunov function such that stability of closed loop system is guaranteed as well as desired performance. Simulation results show that proposed switching strategy improves the performance of the controller and reduces the conservation in comparison with the common H2/H∞ controller.

Relaxed Stability Conditions for Switched Systems with Dwell Time
The paper presents asymptotic, and input-to-state stability results, for switched systems with dwell time in which the switching signal is not arbitrary, but is rather chosen as part of the control design strategy. Then, appropriate switching policies allow the use of functions without sign-definite time derivatives in lieu of a common Lyapunov-like function.
متن کاملSwitching H2/H∞ Controller Design for Linear Singular Perturbation Systems
This paper undertakes the synthesis of a logic-based switching H2/H∞ state-feedback controller for continuous-time LTI singular perturbation systems. Our solution achieves a minimum bound on the H2 performance level, while also satisfying the H∞ performance requirements. The proposed hybrid control scheme is based on a fuzzy supervisor managing the combination of two controllers. A convex LMI-B...
متن کاملInvariance principles for switching systems via hybrid systems techniques
Invariance principles for hybrid systems are used to derive invariance principles for nonlinear switching systems with multiple Lyapunov-like functions. Dwell-time, persistent dwell-time, and weak dwell-time solutions are considered. Asymptotic stability results are deduced under further observability assumptions or common bounds on the Lyapunov-like functions.
متن کاملInput-to-state Stability of Switched Nonlinear Systems
The input-to-state stability (ISS) problem is studied for switched systems with infinite subsystems. By the method of multiple Lyapunov function, a sufficient ISS condition is given based on a quantitative relation of the input and the values of the Lyapunov functions of the subsystems before and after the switching instants. In terms of the average dwell-time of the switching laws, some suffic...
متن کاملSwitching Robust Control Synthesis for Teleoperation via Dwell Time Conditions
Control design for bilateral teleoperation is still an open problem, given that it is desirable to meet a proper balance in the inherent trade-off between transparency and stability. We propose the use of switching robust control, in which smooth switching among controllers is achieved by the existence of multiple Lyapunov functions with a special structure, linked by conditions of maximum aver...
