摘要
This contribution presents a state feedback control and a new disturbance compensation method using the Proportional-Integral-Observer (PI-Observer). For a suitable class of systems the observer estimates the unmeasured states as well as unknown inputs acting on a structure using a small number of measurements. Here, the observer is applied to elastic structures where the PI-Observer can be used for model-based diagnosis and control. An extended disturbance compensation is proposed to improve the dynamical behavior to decouple the effect of disturbances on defined outputs using the PI-Observer The observer and the control are applied to an all side clamped elastic plate. The performance of the control is illustrated by simulation results.
