On the Relationship of Optimal State Feedback and Disturbance Response Controllers
Runyu Zhang, Yang Zheng, Weiyu Li +1
This paper studies the relationship between state feedback policies and disturbance response policies for the standard Linear Quadratic Regulator (LQR). For open-loop stable plants…
Escaping High-order Saddles in Policy Optimization for Linear Quadratic Gaussian (LQG) Control
Yang Zheng, Yue Sun, Maryam Fazel +1
First order policy optimization has been widely used in reinforcement learning. It guarantees to find the optimal policy for the state-feedback linear quadratic regulator (LQR). Ho…
Analysis of the Optimization Landscape of Linear Quadratic Gaussian (LQG) Control
Yang Zheng, Yujie Tang, Na Li
This paper revisits the classical Linear Quadratic Gaussian (LQG) control from a modern optimization perspective. We analyze two aspects of the optimization landscape of the LQG pr…
System-level, Input-output and New Parameterizations of Stabilizing Controllers, and Their Numerical Computation
Yang Zheng, Luca Furieri, Maryam Kamgarpour +1
It is known that the set of internally stabilizing controller is non-convex, but it admits convex characterizations using certain closed-loop maps: a cl…
