Engineering systems, such as engines and manufacturing systems, often exhibit variable operating conditions, variable time-delays and actuator saturation constraints. In this presentation, a unified framework will be presented to address the control design problem for such complex systems using a Linear Parameter Varying (LPV approach). The proposed controllers are scheduled (adapted) based on the current operating conditions, feedback delays and saturation levels. Optimized regulation and disturbance attenuation problems will be examined in this framework. These control design problems can be solved effectively using efficient Linear Matrix Inequality (LMI) optimization algorithms with guaranteed convergence, The treatment of LPV sampled-data control problems with also be discussed.
