The aim of this paper is to investigate the influence of different angle sensors and individual PID control algorithm on the control parameters of the angular positioning system. An overview of precision positioning systems and possible angular measurement sensors, of which three are chosen: magnetic angle sensor A1335, combined with a 12-pole magnet, an incremental optical encoder A58F and laser beam aimed on the TSL1402R linear sensor array. An analysis of angle sensors has shown that the most accurate sensor is an optical encoder, with which an angular positioning system to control a turning point with an accuracy of 0.00168 ̊. The minimum accuracy is achieved using the magnetic angle sensor A1335 along with the 12-pole magnets. The absolute angular positioning error in this case is 0.0561 ̊. A study of the influence of PID control coefficients on the control characteristics of the angular positioning system was also performed. The research confirmed the hypothesis: 1. Sensor resolution has a great influence on the accuracy of angular positioning. 2. In the PID control algorithm integral part has greatest influence on the accuracy of angular positioning. 3. The proportional and integral parts make the greatest impact on the angle overshooting. 4. The integral part of the PID extends the system settling time. |
