Constrained bilinear optimal control of reactive evolution equations
Zhexian Li, Felipe de Barros, Ketan Savla
We consider constrained bilinear optimal control of second-order linear evolution partial differential equations (PDEs) with a reaction term on the half line, where control arises…
A complex spatial frequency approach to optimal control of finite-extent linear evolution systems
Zhexian Li, Athanassios S. Fokas, Ketan Savla
We consider the linear quadratic regulator (LQR) for one-dimensional linear evolution partial differential equations (PDEs) on a finite interval in space. The control is applied as…
Output-feedback adaptive model predictive control for ramp metering: a set-membership approach
Zhexian Li, Ketan Savla
Ramp metering, which regulates the flow entering the freeway, is one of the most effective freeway traffic control methods. This paper introduces an output-feedback adaptive approa…
Adaptive model predictive control for traffic signal timing with unknown demand and parameters
Zhexian Li, Ketan Savla
This paper designs traffic signal control policies for a network of signalized intersections without knowing the demand and parameters. Within a model predictive control (MPC) fram…
