Control of an Oscillatory System
(1997) In MSc ThesesDepartment of Automatic Control
- Abstract
- Systems with structural resonances are difficult to control if fast responses are required. Rapid changes in the control signal may excite the resonant modes. In digital control with zero-order-hold sampling there will be very rapid changes in the control signal. A way to deal with the problem is to use predictive first-order-hold sampling instead. The control signal is then linear between the sampling instants. This thesis investigates trade-offs in control of a typical oscillatory system. PI, PID and state feedback controllers are examined analytically or by simulations with a model of the considered system. A comparison is also made between zero-order-hold and predictive first-order-hold sampling.
