Full-coefficient Intelligent Adaptive Position Control of Permanent Magnet Synchronous Linear Motor
Li Zheng,Wang Kangtao,Wang Jinsong,Zhang Lucheng,Sun Hexu 대한전기학회 2023 Journal of Electrical Engineering & Technology Vol.18 No.3
Permanent magnet synchronous linear motor (PMLSM) can directly convert electrical energy into mechanical energy. Compared with rotary motors, it can not only reduce the energy consumption of the system but also does not require an intermediate transmission device, which improves the operation accuracy and reduces the energy loss caused by mechanical structures such as gears. Given the increasing requirements for the control speed and accuracy of linear motors, a control method that considers both steady-state and dynamic performance is required. Therefore, this paper designs an intelligent adaptive position controller based on the motor characteristic model, and it can be seen through simulation and experiments that the controller designed in this paper has higher steady-state accuracy and faster response than traditional PI control. Speed and other advantages make the linear motor control system have both high control accuracy, fast response speed, strong robustness and other excellent performances, and can replace the work of traditional rotary motors with linear motors.

Study on the Impact of Positioning Errors on the Process Performance of Robotic Bonnet Polishing
Xuepeng Huang,Zhenzhong Wang,Lucheng Li 한국정밀공학회 2023 International Journal of Precision Engineering and Vol.24 No.9
High-precision optical components are widely used in major fields such as strong lasers and astronomy, but the production cycle of components is greatly constrained by the difficulty of machining optical components and the high price of special polishing machines, so it is important to develop a high-efficiency and low-cost fast polishing system for optical components. By combining bonnet polishing technology with industrial robotics, we have developed an industrial robotics bonnet polishing system for optical components, and the effect of robot positioning errors on pad trimming and on the polishing of the entire surface is also analyzed. To verify the processing capability of the robotic bonnet polishing device, polishing pad dressing experiments and optical component surface correction polishing experiments were carried out. After the pad was dressed, the runout value was reduced from 182 to 23 μm with a convergence ratio of 7.9. After polishing the optical component twice, the PV and RMS values on the surface of the component decreased significantly, from 38.05 λ and 9.98 λ to 8.65 λ and 1.38 λ (λ = 632.8) respectively in the middle area of the component, with a convergence ratio of 4.4 and 7.2, proving that the robotic bonnet polishing system can be applied to the polishing process of optical components.
