Control Systems Webinar | Delayed and Sampled-Data Control of PDEs by Prof Emilia Fridman
The fifth international e-seminar of 2021 on systems and control theory will be presented by Prof. Emilia Fridman from Tel Aviv University, Israel.
Abstract:
The talk will start with distributed control and estimation of semi-linear 1D heat equations in the presence of input/output delays (which may include sampling in time). It will present sampling in space (or spatial decomposition) method, where the domain is divided into N subdomains with N sensors located in each subdomain, whereas the control is applied through distributed in space shape functions.
Given upper bounds on the delays, sufficient conditions ensuring the stability and performance are established in terms of LMIs via appropriate Lyapunov functionals and Halanay’s inequality. The results will be applied to a network-based deployment of multi-agents. Extensions to N-D heat, Kuramoto-Sivashiskii, damped wave, and other PDEs will be discussed.
For boundary control, delay compensation via sub-predictors will be considered. Finally, recent results on finite-dimensional observer-based control of 1D parabolic PDEs via modal decomposition will be presented.
