In conventional motion control systems, optical encoders or electromagnetic resolvers are used for this purpose. 在傳統的運動(dòng)控制系統中，通常采用光電編碼器或旋轉變壓器來(lái)檢測轉子的位置和速度。
The photoelectric encoder is used for measuring the angular position of rotating ballscrew.Semi closed loop compensation control is realized and system accuracy is improved. 應用光電編碼器作為滾珠絲杠轉角位置檢測元件實(shí)現了半閉環(huán)補償控制，提高了系統的精度。
