Robust control of uncertain resonant systems using pole-placement [discrete-time systems]

The growing demand for advanced control applications such as light flexible structures on the one hand, and the availability of increased computation power on the other, mark the trend to relax the requirements from mechanical systems and use more sophisticated control algorithms to maintain high performance with cheaper and lighter plants. In this work we present results which apply to design of resonant plants. An approximation of closed loop properties of low damping resonance is presented, together with a combined pole-placement transfer value equations. A design approach is suggested for determining the low frequency performance by pole specifications and the high frequency resonance handling by frequency domain considerations.
