| Abstract | ||
| ABSTRACT An electro-hydraulic control system is designed to control the demining depth of a mine plough machine equipped with plough blade of “V” type. A Linear Variable Differential Transformer (LVDT) is used to account for blade position and an ultrasonic distance sensor is used to provide precise, non-contact, level distance measurements through dusty environment. The proposed control system is implemented to the operating hydraulic system of a scaled model of a plough mechanism. The operating hydraulic actuators used to control the plough mechanism are controlled through a microcontroller and system relays to maintain plough blade depth constant. Results show that significant match between operating surface topology and clearing depth is validated by the proposed control system. | ||
