| Abstract | The aim of this study was to design the servo electro-hydraulic system for doubleshank vibrating subsoiler by using a Fuzzy - based frequency control as compared toproportional?integral?derivative (PID) frequency control. The steady vibration of subsoilerwas controlled to enhance the subsoiler?s performance and convenient to change thefrequency level. After inputting a preferred frequency through the controller, aproportional valve was opened to control a flow rate of hydraulic oil into the hydraulicmotor which connected to the vibration system. This process was measured by sensors,transducers and feedback signal processing devices. The experiments were conducted insandy clay loam soil of 20.60% (db) moisture content, 1.66 g/cm3 dry bulk density and2.58 MPa cone penetration resistance at a forward speeds of 2.09 km/h, a tillage depthsof 30 cm, a constant oscillatory amplitude of 36.5 mm and three oscillatory frequencies(7, 9 and 11 Hz). The experimental results showed that both controllers efficientlycontrolled the stable oscillatory frequency for a tillage. However, the fuzzy-based controlperformed better response than the PIDcontroller. Fuzzy-based controller hadhigher speed and more accuracy than PIDcontroller which had high overshoot. |
