Structural dynamics can introduce low-frequency modes that must be considered for modeling and control of  exible aircraft. Furthermore, the modal dynamics can be affected by operating conditions such as temperature. A linear parameter-varying (LPV) framework is used to represent structural dynamics. The framework represents the dynamics with dependency on operating parameters as a set of stat...

Active power control (APC) refers to a mode of operation where the wind turbine tracks a desired power reference command. It enables wind farms to perform frequency regulation and to provide ancillary services in the energy markets. This paper presents a linear parameter varying (LPV) approach for APC. The multiple-input, multiple-output controller builds upon a previous gain-scheduled design. ...

This paper is devoted to the problems of gain-scheduled control for a class of discretetime stochastic systems with infinite-distributed delays and missing measurements by utilizing probability-dependent Lyapunov functional. The missing-measurement phenomenon is assumed to occur in a random way, and the missing probability is time varying with securable upper and lower bounds that can be measur...

This paper presents a new methodology for the design and implementation of gain-scheduled controllers for multi-rate systems. The proposed methodology provides a natural way to address the integrated guidance and control problem for autonomous vehicles when the outputs are sampled at different instants of time. A controller structure is first proposed for the regulation of non-square multirate ...

this paper proposes a new method of gain scheduling control design for a nonlinear system which is described as linear parameter varying form. a performance measure based on linear matrix inequality is introduced. to consider stability and performance measures in design process, the h∞ loop-shaping method is used to design the local controllers, which can be described as state feedback observer...

The paper addresses the problem of autonomous underwater vehicle (AUV) control in the absence of full state information. An application is made to the control of a prototype AUV in the vertical plane. The methodology adopted for controller design is nonlinear gain scheduling control, whereby a set of linear, dynamic reduced order output feedback controllers are designed and scheduled on the veh...
