	1	Nonlinear robust H-infinity filtering for a class of uncertain systems via convex optimization显示文摘A new approach for robust H-infinity filtering for a class of Lipschitz nonlinear systems with time-varying uncertainties both in the linear and nonlinear parts of the system is proposed in an LMI framework. The admissible Lipschitz constant of the system and the disturbance attenuation level are maximized simultaneously through convex multi-objective optimization. The resulting H-infinity filter guarantees asymptotic stability of the estimation error dynamics with exponential convergence and is robust against nonlinear additive uncertainty and time-varying parametric uncertainties. Explicit bounds on the nonlinear uncertainty are derived based on norm-wise and element-wise robustness analysis.	Masoud ABBASZADEH Horacio J. MARQUEZ	2012	控制理论与应用(英文版)2012，10，2：	2
	2	Non-linear optimal control for multi-DOF electro-hydraulic robotic manipulators显示文摘A non-linear optimal(H-infinity)control approach is proposed for the dynamic model of multi-degree-of-freedom(DOF)electro-hydraulic robotic manipulators.Control of electro-hydraulic manipulators is a non-trivial problem because of their non-linear and multi-variable dynamics.In this study,the considered robotic system consists of a multi-link robotic manipulator that receives actuation from rotary electro-hydraulic drives.The article's approach relies first on approximate linearisation of the state-space model of the electro-hydraulic manipulator,according to first-order Taylor series expansion and the computation of the related Jacobian matrices.For the approximately linearised model of the manipulator,a stabilising H-infinity feedback controller is designed.To compute the controller's gains,an algebraic Riccati equation is solved at each time-step of the control algorithm.The global stability properties of the control scheme are proven through Lyapunov analysis.The proposed control method retains the advantages of typical optimal control,i.e.fast and accurate tracking of the reference setpoints under moderate variations of the control inputs.
