Characterizing all PID gains that guarantee uniform exponential regulation of uncertain nonlinear systems remains a fundamental problem. Most existing results provide only sufficie…
On Global Regulatability of Robot Manipulators by Classical PID
Cheng Zhao, Jingru Zhu, Lei Guo
A long-standing open problem in robot manipulator control is whether global regulation can be achieved by classical PID control. This paper provides an answer to this question for…
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,…
Theory and Design of Extended PID Control for Stochastic Systems with Structural Uncertainties
