Design of an airborne dust control system in ventilated animal housing

AbstractThe dynamics of a lumped-parameter model for describing the behavior of airborne dust in animal housing are used in the development of controllers for an airborne dust control system. Proportional (P) and Proportional-integral (PI) feedback controllers designed from the viewpoint of modern state-variable control theory are used as an airborne dust control system in ventilated animal housing. Linear quadratic regulators (LQRs) with output feedback control of a linear-invariant system are chosen for this study. The plant is represented by a linear dynamic equation that describes the dynamic behavior of airborne dusts undergoing turbulent diffusive deposition and gravitational settling in a ventilated airspace. To illustrate this procedure, the design was applied to control the dust concentration in typical animal housing
