Mechatronic system for air pressure control

The mechatronic system for air pressure control proves that the system design in order to obtain maximum operating performance. The evolution in the "embedded systems" domain related with the apparition of some new sensor types permits the integration of the pressure sensor and the smart pressure regulator, based on a microcontroller solution, in the mechanical ensemble. The execution part in the system is a force electromagnet which transforms the driving current in mechanical force. In an innovative way, protected by patent, this force controls the output pressure. The output pressure is monitored with an integrated in silicon pressure sensor. The measured value of the pressure is compared with the desired value; the pressure error signal is amplified and used to drive the force electromagnet. The mechatronic system is controlled through serial bus, RS232 or RS485 type. The experimental results prove that the operating performance in static and dynamic behaviors.
