讲座内容：

The goal of set-membership estimation is to compute sets of admissible values of the state vector at each instant of time for systems subject to bounded uncertainties such as measurement noise, disturbances and uncertain parameters. The size of the estimated sets, which should be minimized, has to be proportional to the model uncertainties. A set estimation can be seen as a conventional point estimation (the center of the set) with an estimation error given by the radius of the geometrical set. The reliable uncertainties propagation performed in this context can be useful in several fields such as robust control, diagnosis and fault-tolerant control. During this lecture some recent results developed for linear and nonlinear systems (both continuous and discrete-time cases) based on ellipsoids and intervals will be presented. Based on numerical simulations, it will be shown that these innovative approaches can overcome the limitations of standard interval observer techniques.
