Advanced Linear Proportional Control of a Pressure Valve for an Electric Pressure Cooker

This paper describes the advanced control of solenoid for pressure valve for electric pressure cooker. To remove the problem of the on/off non-proportional pressure control method which was used to control the existing solenoid, newly redesigned solenoid was adopted and the advanced control method, linear proportional control method, was proposed. The control system by the pressure sensor and AVR was manufactured and its validation was proved through the experiment.
