IFT-LPV: Data-Based Tuning of Fixed Structure Controllers for LPV Systems

IFAC-PapersOnLine, 2015
Fixed structure controllers are widely used, however the tuning thereof can be cumbersome and gives no guarantee of optimality, especially when the system is Linear Parameter-Varying (LPV). Iterative Feedback Tuning (IFT) is a technique for the optimisation of a parameterised controller based on closed-loop experiments.

Detection and Identification of Loss of Efficiency Faults of Flight Actuators

International Journal of Applied Mathematics and Computer Science, 2015
We propose linear parameter-varying (LPV) model-based approaches to the synthesis of robust fault detection and diagnosis (FDD) systems for loss of efficiency (LOE) faults of flight actuators.

An Offline Formulation of MPC for LPV Systems Using Linear Matrix Inequalities

Journal of Applied Mathematics, 2014
An offline model predictive control (MPC) algorithm for linear parameter varying (LPV) systems is presented. The main contribution is to develop an offline MPC algorithm for LPV systems that can deal with both time-varying scheduling parameter and ...
