The process of roadway surrounding rock deformation and instability is always accompanied by energy changes, and the energy transformation of surrounding rock directly drives its deformation and failure.In order to realize the stability control of mining roadway, the distribution of elastic strain energy and plastic strain energy of surrounding roc
Given the problem of three-sources uncertainty in aero engine degradation process and the assumption of normal distribution of measurement error in existing research, a Wiener process aero engine Moulds and Bakeware residual useful life time(RUL) prediction method with logistic distribution of measurement error was proposed.Firstly, the performance
This paper presents a comprehensive evaluation of the effect of quasi oppositional - based learning method utilization in output tracking control through a swarm-based multivariable Proportional-Integral-Derivative (SMPID) controller, which is tuned by a novel performance index based on the step response characteristics in multi-input multi-output
