Design and Verification of Adaptive Adjustable Output Control on Micro Spray Gun

The general spray gun is used for industrial large-area spraying, and there less demand different pressures the accuracy of spraying pressure, so mechanical pressure regulators are mostly used. However, as artistic innovation continues to grow, it promotes advent micro gun. currently commonly known an airbrush. mainly fine drawing, must provide with high precision pressures, but existing cannot meet this requirement. For these unmet requirements, study proposed a solution PID (proportional-integral-derivative) control system. results showed that could effectively various stable output pressure-varying range 30 kPa rapidly return target value in 10 s (the usual time). then presents better effects.
