Abstract: Presently, there are good positioning systems for drilling tools but the challenging problem is that accuracy of positioning drops as the speed of operation of the system is increased. This paper obtained the dynamical model of the drilling tool positioning system. To improve positioning accuracy, a lead phase digital compensator was designed and added to the original plant or process to improve the transient response of the system in other to achieve a settling time of less than 12 seconds. The compensator parameters were obtained using MATLAB tuning tool and the entire design accomplished with the time domain analysis method. A digital controller with maximum overshoot less than 29% , a rise time of 1.59 seconds with a 2% criterion and a settling time of 8.8 seconds was obtained.
Keywords: positioning system, machine tools system, transfer function, digital compensator, and response.
