A torque control system of Permanent Magnet Synchronous Motor (PMSM) is an important process in industries, especially in the hard disk drive assembly processes. For example, the automatic screw machine is one of important machines in the hard disk drive assembly processes. The PMSM is a fundamental component of the automatic screw machine. The feedback torque control system use estimated torque received from motor current. The disturbance torque caused by the screw process depends on the quality of the screw heads and screw holes. The automatic screw machine requires precise output torque because the error of output torque affects the automatic screw machine performance. The damage in the hard disk drive assembly process may result from an inaccurate output torque. For instance, the defect of product is broken threads of the screws and the out of length of the screw heads. When the control process requires precision output torque, the machines must be calibrated by operator with standard value consumed 20-30 minutes per machine. This paper presents a torque control system with an adaptive fuzzy logic compensator for torque control and torque estimation simultaneously. The method of the research can increase the efficiency of torque control system and decrease the calibration time of the automatic screw machines.

“…A nonliniear control system approach for a DC motor such as a sliding mode control design as in [5], backstepping control as in [6,7], and an adaptive control as in [8][9][10][11][12][13] have been discussed. Based on paper as in [5][6][7][8][9][10][11][12][13], the adaptive control approach is the most suitable type of control to treat conditions such as the disturbance of a DC motor. So, we used the adaptive control based on Model Reference Adaptive Control (MRAC) to control our DC motor model.…”

Sometimes the conventional feedback control can not work well to cope with the changes that vary in its dynamic system. The parameters of the dynamic system that changes with time lead to a conventional feedback control system is not able to maintain control. This is caused by circumstances which are nonlinear and receive many disturbance so that the transient response of the system to be less precise and accurate to the desired steady state conditions. To overcome these problems, this paper presents an adaptive control system which can cope with the change of the dynamic DC motor system. The adaptive control system used is Model Reference Adaptive Control (MRAC) which contain four part. They are reference model, adaptation mechanism, plant, and control law. We designs DC motor plant by using Simscape in Simulink. An ideal response for reference model is designed by modeling the dynamic DC motor. Design of an adaptation mechanism with MIT rule and control law with Proportional Integral Derivative (PID) controller are present. It can affect the response of adaptive control system and matching the desired ideal response from reference model even when the system receives a disturbance.

Finger traps are a valuable tool that can be maintained the traction. The devices stretch the thumb and other four fingers separately in order to achieve better reduction effect. These are applied individually to the fingers and the limb is suspended, with gravity providing counter-traction to disimpact the fracture by traction. However, personal gravity can’t be used to maintain the appropriate tension. This paper proposed an experimental study on the tension of counter-traction mechanism to finger traps for fracture reduction. This mechanism is particularly useful to help for the patients. Transfer function estimation from experimental data can improve the overall identification performance and the parameter. The feedback control system design for compensating tension that loses from disturbance tension consisted of the controller as PI controller and actuator as DC motor with counter-traction mechanism. Experimental results were demonstrated the efficiency of the proposed system to maintain the appropriate tension.
