This paper proposes a long travel range electromagnetically actuated positioning stage with application to micro machining. Specially, a probe with titanium coating is integrated with an electromagnetically actuated and damped positioning stage to perform millimeter range movement. Here, the developed stage replaces traditional piezoelectric actuators for the purpose of lengthening the motion range...
This paper describes the design of robust and anti-windup controllers for an air-breathing hypersonic vehicle model. Firstly, a control algorithm is presented to design robust and anti-windup controllers for linear systems with modeling uncertainties and input saturation nonlinearities. Based on the characterization of modeling uncertainties and saturation nonlinearities via integral quadratic constraints...
For an air-breathing hypersonic vehicle model subject to input constraints, this paper is concerned with the application of linear control theory to design its flight control system. In the framework of integral quadratic constraints (IQCs), the standard linear parameter-varying (LPV) control method is generalized to deal with the parametric, dynamic uncertainties and saturation nonlinearities associated...
In this paper, properties of dichotomy for nonlinear systems with norm-bounded uncertainty are considered. By using some results of Hinfin theory and method of linear matrix inequality (LMI) some criterions of testing robust dichotomy of uncertain nonlinear systems are given. An approach of designing state feedback controller guaranteeing dichotomy of closed loop systems with norm-bounded uncertainty...
This paper is concerned with the problem of global behavior analysis for a class of nonlinear systems with parameter uncertainties in the feedforward path and a periodic nonlinear function in the feedback path. Based on the frequency domain methods, sufficient criteria of robust global behavior for such systems are derived. An example illustrating the numerical implementation of the main results is...
This paper focuses on uncertain pendulum-like systems subjected to norm-bounded parameter uncertainty in the forward path and a vector-valued periodic nonlinearity in the feedback path, and addresses the robust gradient-like behavior analysis and synthesis problems for such systems. Sufficient conditions for robust gradient-like behavior are derived in terms of linear matrix inequalities (LMIs) and...
