Exact PID and PI Gain Regions for Uncertain Non-Affine MIMO Systems
Cheng Zhao
Characterizing all PID gains that guarantee uniform exponential regulation of uncertain nonlinear systems remains a fundamental problem. Most existing results provide only sufficie…
Towards Guaranteed Optimal PID Tuning for Uncertain Nonlinear Systems
Jingru Zhu, Cheng Zhao, Lei Guo
Despite the widespread use of PID controllers in engineering practice, designing optimal PID parameters has long been regarded as a challenging problem in both theory and practice,…
Necessary and Sufficient PID Gain Regions for Global Stabilization of Uncertain Second-Order MIMO Nonlinear Systems
Tianyou Xiang, Cheng Zhao
As is well known, classical PID control is ubiquitous in industrial processes, yet a rigorous and explicit design theory for nonlinear uncertain MIMO second-order systems remains u…
Tracking performance of PID for nonlinear stochastic systems
Cheng Zhao, Shuo Yuan
In this paper, we will consider a class of continuous-time stochastic control systems with both unknown nonlinear structure and unknown disturbances, and investigate the capability…
Understanding the Capability of PD Control for Uncertain Stochastic Systems
Cheng Zhao, Yanbin Zhang
In this article, we focus on the global stabilizability problem for a class of second order uncertain stochastic control systems, where both the drift term and the diffusion term a…
