Thesis: “Robust State Filter and LQG Regulator of a Discrete-Time Linear

Descriptor System with Uncertain Noises”
Research Areas:

● Jump linear systems: The overall system jump among individual linear subsystems. When the jumping rule is governed by a Markov chain, it becomes Markovian jump linear systems. I investigate stability, performance of such Markovian jump linear systems.

● Networked control systems: When the control feedback is closed over digital network, we get a class of networked control systems. Due to insertion of non-deterministic digital network, the feedback information can be unreliable and have finite precision. What are the effects of such non-ideal features on stability and performance of control systems? How can these effects be mitigated? They are mainly my research topics.

● Signal processing and communication: My research is mainly on data storage systems, more specifically on servo demodulation systems. I study timing recovery, servo demodulation (head position estimation from the servo readback signal), servo pattern design, joint design of servo demodulation and servo control systems, etc.
