| Research Abstract |
This research has investigated a stabilization problem for time-delay systems, in theory and simulation. Some theoretical results have been obtained in the following.
- The stabilization problem with time-delay is reduced into a phase margin specification problem for zero time delay systems.
- It is shown that the phase margin specification problem is equivalent to an H-infinity control problem ; cons equently, the problem is easy to solve by conventional control design methods.
Simulations have been executed.to illustrate the theory as below.
- Control system design of airplane has been simulated along the MIL Specification.
- Experimental simulations for control system of flexible structures have been executed.
In summary, this research has theoretically developed a control design method for time-delay systems and the results have been verified by experimental simulations, for physical systems with time-delay.
