Optimum Multivariable Wind Tunnel System Control

Abstract

The control of multivariable system models following input set point and load disturbance changes is considered. An inner and outer loop control strategy is proposed, for analysis purposes, enabling targeted recovery rates, off-set attenuation and constrained steady state interaction to be achieved. Proportional control and passive network compensation alone are employed. Gain ratio selection, ensuring energy efficient confinement of output perturbations, following low frequency load disturbances and reference input changes, is exercised. Disturbance suppression and transient recovery rate adjustment, via outer loop feedback advancement, is advocated. An application study is presented for purposes of illustration, confirming the theoretical predictions thereby.
