“…al. [4] also researched precision positioning of a DC motor, but in the presence of aerostatic friction, and they used a PID controller as well. Although many advanced control algorithms were used, PID control method has proved its efficiency, robustness, and considered to be fully effective for various DC Motor applications.…”

Abstract. This paper presents the design of a robust control system for a PMDC motor using LabVIEW software. At first, the mathematical equations of the motor were modelled and simulated. Then, a proportional integral controller (PI) was used as a speed controller, and to guarantee the robustness of the system against the disturbances, the PI parameters were tuned by applying a sensitivity analysis. Finally, a proportional gain (P) was used as a position controller to guide the system towards the desired angle. The simulation was performed using LabVIEW Simulation Loop, and the sensitivity analysis was carried using LabVIEW MathScript tool.

“…The friction force between the moving part and the surrounding fixed components may cause positioning error due to the nonlinear behavior. Friction force usually degrades the dynamic performance and positioning accuracy, and can also lead to steady state error (Mao et al, 2003). Therefore, the system which can compensate the gravity load in a perfect noncontact condition is required.…”

In vertical positioning systems, the friction force and the gravity load cause significant error. In order to minimize the effect of friction and gravity load, this paper presents the noncontact gravity compensator applying magnetic fluid seals. The structure of the magnetic fluid seals was proposed for the linear motion system, and the dimensions of the magnetic fluid seal components were determined based on the result of the magnetic field analysis using FEM. Magnetic field analysis was used in order to investigate the relationship between the seal capacity and varied dimensions. Based on the results of the analysis, several types of magnetic fluid seal units were manufactured, and the analytical results were compared with the results of the seal capacity evaluation experiment in order to confirm the validity of the magnetic field analysis. In addition, the gravity compensating system using the magnetic fluid seals was constructed and applied to a vertical positioning system. Positioning resolution was evaluated with stepwise positioning experiments. Tracking performance and the response of the pressure were evaluated by the continuous path control experiment. According to these experimental results, the effectiveness of the gravity compensator with magnetic fluid seal was confirmed.
