QoS aware joint observer and networked PI/PID controller design using LMIs under specified rate of packet dropouts

作者：

Highlights：

• NCS under specified packet drop rate has been stabilized using Lyapunov stability and LMI.

• Switched system and non-convex LMI formulation has been solved using CCL algorithm.

• Joint PI/PID controller and observer are designed for the NCS with specified QoS.

• Performance comparisons are reported using Monte Carlo simulation for 50% and 90% packet drop rates.

• DC-DC converter and synchronous generator are considered as two test-bench plants for validation.
