    摘要: A controller unit includes a PI-controller for harmonic command variables. The transfer function of the PI-controller has a conjugate complex pole at a controller angular frequency ωr in the s-plane or a pole at e±jωrT in the z-plane, wherein T is the sampling time of a discrete input signal of the PI-controller and ωr is larger than 0. The controller angular frequency ωr is chosen equal to the resonance angular frequency ω0 of an oscillator. The controller parameters, are, for example determined by pole/zero compensation. The controller unit allows, for example, a broad band control of harmonic oscillators in rotation rate sensors.
