Hybrid self-tuning controllers are introduced which combine two sample rates to give both discrete time and continuous-time features. The limiting properties of such algorithms, as the sample rate increases, are shown to correspond to a continuous-time control law. Undesirable intersample behaviour associated with the discrete-time control of continuous systems with high pole-zero excess is thus avoided. The results are illustrated by the control of a triple integrator.
