Pole-placement controllers for linear systems with point delays

This paper presents a robust control algorithm for plants involving both internal (i.e. in the state) and external (i.e. in the output or input) known point delays. Several stabilizing controller structures are given and analysed for the case of perfectly modelled plants with known parameters. The parametrized parts of two of the controller structures involve delays, while those of the two remaining controllers are delay-free. However, auxiliary compensating signals which weight the plant input and output integrals are incorporated in all the controller structures for stabilization and model matching purposes.
