Quantitative unique continuation and observability on an equidistributed set for the diffusion equation in R^N
Yueliang Duan, Huaiqiang Yu, Can Zhang
In this paper, we obtain a quantitative estimate of unique continuation and an observability inequality from an equidistributed set for solutions of the diffusion equation in the w…
Exponential stabilization on infinite dimensional system with impulse controls
Qishu Yan, Huaiqiang Yu
This paper studies the exponential stabilization on infinite dimensional system with impulse controls, where impulse instants appear periodically. The first main result shows that…
Switching properties of time optimal controls for systems of heat equations coupled by constant matrices
Shulin Qin, Gengsheng Wang, Huaiqiang Yu
This paper studies the time optimal control problem for systems of heat equations coupled by a pair of constant matrices. The control constraint is of the ball-type, while the targ…
Constrained approximate null controllability of coupled heat equation with periodic impulse controls
Lijuan Wang, Qishu Yan, Huaiqiang Yu
This paper is concerned with the constrained approximate null controllability of heat equation coupled by a real matrix , where the controls are impulsive and periodically acted…
On switching properties of time optimal controls for linear ODEs
Shulin Qin, Gengsheng Wang, Huaiqiang Yu
In this paper, we present some properties of time optimal controls for linear ODEs with the ball-type control constraint. More precisely, for an optimal control, we build up an upp…
Stabilization on periodic impulse control systems
Shulin Qin, Gengsheng Wang, Huaiqiang Yu
This paper studies the stabilization for a kind of linear and impulse control systems in finite-dimensional spaces, where impulse instants appear periodically. We present several c…
