Discrete-time Lpv Controller for Robust Missile Autopilot Design
نویسندگان
چکیده
This paper proposes a method to obtain a discrete-time LPV (Linear Parameter Varying) controller for a non-linear system represented with the LFT (Linear Fractional Transformation) framework. This synthesis can be integrated into a loop-shaping/LPV approach to obtain a discrete gain-scheduled control law. A detailed application of this method is here performed with a classical example of non-linear missile pitch-axis control. Copyright © 2002 IFAC

Systematic Gain-scheduling Control Design: a Missile Autopilot Example
The missile autopilot was designed using linear parameter-varying (LPV) control techniques. The controller provides exponential stability guarantee and performance bound in terms of induced L2 norm for the missile plant. The systematic gain-scheduling approach is motivated by the recent development in LPV control theory and provides a well founded and systematic procedure for high performance m...
متن کاملRobust H2 switching gain-scheduled controller design for switched uncertain LPV systems
In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
متن کاملRobust Fixed-order Gain-scheduling Autopilot Design using State-space Stability-Preserving Interpolation
In this paper, a robust autopilot is proposed using stable interpolation based on Youla parameterization. The most important condition of stable interpolation between local controllers is the preservation of stability so that each local controller can ensure stability for an open neighborhood around a nominal point. The proposed design used fixed-order robust controller with parameter-dependent...
متن کاملSelf-scheduled H 1 Control of Linear Parameter-varying Systems: a Design Example
This paper is concerned with the design of gain-scheduled controllers with guaranteed H1 performance for a class of Linear Parameter-Varying (LPV) plants. Here the plant state-space matrices are assumed to depend aanely on a vector of time-varying real parameters. Assuming real-time measurement of these parameters, they can be fed to the controller to optimize the performance and robustness of ...
