Study on the control object of pressure-boosting switching air supply system

摘要

A pressure-boosting switching air supply system (PBSASS) discussed in this paper contributes a new principle for pressurization. Since both the output pressure and the volume flow rate of pneumatic inductor represent the energy stored in the system, the control objects of the PBSASS are not obvious as traditional pressurize devices. The result of the mathematical simulation shows when controls the output pressure and the volume flow rate separately, the controllability of the system is defected. But the system obtains good stability and tracking ability when control the product of these two values.
