Preview control has been explored in the context of linear and nonlinear inverse tracking controllers. Preview of the reference trajectory has been shown to give significant performance advantages, particularly for plants that do not possess a stable inverse. Without preview, it has been known that lack of a stable inverse imposes inherent limitations on the achievable tracking performance of a control loop. This has been explored in the context of time and frequency domain integral constraints. In this paper, we explore the extension of these performance limitations to the preview control case. In particular, we consider the infimal achievable performance, H-infinity and Poisson sensitivity integral results. We also briefly discuss tracking sensitivity properties of preview control.
