Precision versus intelligence: Autonomous supporting pressure balance control for slurry shield tunnel boring machines

This paper presents a method for the autonomous control of supporting pressure balance for a slurry shield tunnel boring machine. The mechanism of multi-system coupling interactions of the slurry supporting process is revealed by establishing the dynamic model of the process. Furthermore, the degree of controllability of the manipulated inputs is analyzed and verified theoretically using singular value decomposition. Based on the analysis of the...
