Left: An example of an NCS. The proposed method is used to design a controller.
Right: H-infinity norm of the system vs. loss probability
(solid: proposed controller, dash: fixed controller from standard H-infinity control).
Networked control system (NCS) is a control system operated over a communication network.
The performance of NCS is often degraded by the problem of data loss in a network.
We model data loss as a stochastic process and propose a stochastic control approach.
To enhance the performance, the controller depends on the loss information and can be
gain-scheduled according to each loss probability.
Two years of performing research on a highly mathematical framework have been very challenging.
Along with the research result, I have obtained a lot of technical knowledge and problem-solving skills.
