Objective To develop a control system with high reliability,full function and fast response for manned centrifuge so as to ensure its smooth operation. Methods According to the function and structure design of manned centrifuge and the control function of PMAC multi-axis motion control card,a manned centrifuge control system was built based on motion controller + PC and absolute encoder feedback was used to control the precision. The software control strategy was to focus on abnormal operation detection and motor stability control. The accuracy test program was designed and 6 volunteers participated in the manned experiment to test the stability of manned centrifuge. Results The designed control system had high control precision. When the rotating speed of the centrifuge was 5,10,15,20 and 25 r/min,the average value of rotating a certain number of cycles was quite close to the set value,the operation of the centrifuge was very stable,and reached the expected requirement. Conclusion The developed centrifuge control system could realize stable and reliable operation. The centrifuge can be applied to the experimental research of human physiological system response in high acceleration environment.
