On Irregular Linear Quadratic Control

Title: On Irregular Linear Quadratic Control


    Speaker: Huanshui Zhang (Shan Dong University)


    Time and venue :Jan 9, 15:00-16:00, N219

 

Abstract: This talk is concerned with a fundamental problem of linear quadratic (LQ) with irregular Riccati equation. Different from the classical control theory for regular LQ problems, a new approach of 'multi-layer optimization' is proposed. With the approach, we show that different controller entries of irregular-LQ controller need to be derived from different equilibrium conditions and a specified terminal constraint condition in different steps, which is much different from the classical regular LQ control where the all the controller entries can be obtained from equilibrium condition in one step based on regular Riccati equation. The presented results clarify the differences of open-loop control from closed-loop control in the aspects of solvability and controller design and also explores in essentially the differences of regular control from irregular control.
