Preliminary Analyses and Simulations for the Application of Modern Control Methods to Mine Ventilation
- Publisher: Department of Control Engineering, University of Sheffield, Mappin Street, Sheffield
Linear dynamics analysis is carried out of some simple mine ventilation networks to assess the likely instability and interaction problems to be encountered in the comprehensive multivariable control of air flow around a mine. It is shown that distributed mine capacitance alone does not generate serious instability problems under closed loop control but interaction elimination requires rather either tailored diagonalising control structures or high gains in multiple diagonal controllers. The interaction of roadway and fan dynamics yields an overdamped system so permitting the use of high controller gains. The report is written also to provide an analytical check on computer simulations of mine ventilation control systems.
