Concentration of Stochastic System Trajectories with Time-varying Contraction Conditions
Zishun Liu, Liqian Ma, Hongzhe Yu +1
We establish two concentration inequalities for nonlinear stochastic system under time-varying contraction conditions. The key to our approach is an energy function termed Averaged…
Optimal Covariance Steering of Linear Stochastic Systems with Hybrid Transitions
Hongzhe Yu, Diana Frias Franco, Aaron M. Johnson +1
This work addresses the problem of optimally steering the state covariance of a linear stochastic system from an initial to a target, subject to hybrid transitions. The nonlinear a…
Data-driven optimal control under safety constraints using sparse Koopman approximation
Hongzhe Yu, Joseph Moyalan, Umesh Vaidya +1
In this work we approach the dual optimal reach-safe control problem using sparse approximations of Koopman operator. Matrix approximation of Koopman operator needs to solve a leas…
Covariance Steering for Nonlinear Control-affine Systems
Hongzhe Yu, Zhenyang Chen, Yongxin Chen
We consider the covariance steering problem for nonlinear control-affine systems. Our objective is to find an optimal control strategy to steer the state of a system from an initia…
