This paper proposes the design and implementation of torque control and torque estimation for an electric hand-tool. This hand-tool does not require any torque transducer or any Hall-effect sensor. Only some low-cost resistances are used to measure the stator currents of a brushless DC motor, which is used to drive the hand-tool. Novel 3-phase current commands are proposed here to obtain greater torque than traditional 3-phase, square-wave current commands. The output torque of the hand-tool can be estimated and displayed by an LED display. A PI controller is used to achieve the current-loop control. A digital signal processor, TMS-320-F2808 that was manufactured by Texas Instruments, is used to execute the control and estimation algorithms. Experimental results show the correctness and feasibility of the proposed methods.

by Kaijun Li, Zibo Di

Frontiers of Mechatronical Engineering, Vol.2, No.2, 2020; 255 Views, 7 PDF Downloads

As one of the important technologies in the mining industry, the drilling machine technology can improve the efficiency and quality of the mining industry. Compared with the traditional drilling machine technology, the drilling machine automation technology is obviously more reliable. Drilling automation technology can not only optimize the traditional mining efficiency, but also ensure the safety of people in the mining process. At present, the automatic drilling machine is the highest level of drilling technology in China. In the process of the automatic drilling machine, the downhole closed-loop technology can be used. This technology can completely separate from the human control and automatically complete the task only by transferring the information to the underground central computer.
