Modeling challenges deterministic modeling: most current models aim at including more physics, not on modeling uncertainty data sets: quality varies, data such as from satellite requires processing/interpretation (models) sub-grid uncertainty: important fine-scale variation (clouds) have global impact.
Uncertain state-space (uss) models are linear systems with uncertain state-space matrices, uncertain linear dynamics, or both. Most functions that work on numeric lti models also work on uss models. These include model interconnection functions such as connect and feedback, and linear analysis functions such as bode and stepinfo.

Modeling gain and phase variations in your uncertain system model lets you verify stability margins during robustness analysis or enforce them during robust controller design. Use the umargin control design block to represent gain and phase variations in feedback loops.
This paper addresses the trajectory tracking problem of nonholonomic vehicles in the presence of uncertainties. Kinematic perturbations stem from skidding of wheels, lateral slips, parametric uncertainties in the kinematic models, external disturbances and other unknown and unpredictable kinematic features. The control algorithm should be capable of compensating these effects.

In this paper we extend the classical min–max model predictive control framework to a class of uncertain discrete event systems that can be modelled using the operations maximization, minimization, addition and scalar multiplication, and that we call max–min-plus-scaling (mmps) systems.
Dealing with and understanding the effects of uncertainty are important tasks for the control engineer. Reducing the effects of some forms of uncertainty (initial conditions, low-frequency disturbances) without catastrophically increasing the effects of other dominant forms (sensor noise, model uncertainty) is the primary job of the feedback control system.
