The primary concept is to unify all intricate factors, including internal dynamics and external bounded disturbance, into a single total disturbance. This enables the mapping of various nonlinear systems onto a linear disturbance system. Based on the theory of PID control and the characteristic equation of a critically damping system, Zeng’s stabilization rules (ZSR) and an ACPID control force based on a single speed factor have been designed. ACPID control theory is both simple and practical, with significant scientific significance and application value in the field of control engineering.展开更多

This paper elaborated human settlement characteristics of ancient Dongyuan Zengs' Village, Jinxi County from the perspectives of village environment, history evolution, village layout and village building, and explored the substantial content of village human settlement protection, and proposed specifi c approaches of protecting the human settlement, such as ancient village layout, history and culture, and provided references for protecting human settlement of the ancient villages.展开更多
