Control of an Oscillatory System

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.
