In order to meet the requirement of rapid attitude maneuver control and vibration suppression of flexible spacecraft with disturbance and uncertainty, this paper presents a robust control scheme based on path planning and adaptive backstepping control. Firstly, a novel path planning scheme is proposed based on quintic polynomial transition. The continuous and smooth maneuver path is designed to solve...
In this paper the robot leg virtual prototype is established through the simulation analysis software, and a feedback control system based on the robot body platform acceleration has been designed to study the strategy for optimizing the stability control of the robot during the walking process. The virtual prototype is imported to MATLAB and the ADRC algorithm is designed to suppress the low frequency...
A well-designed space microgravity environment is an important guarantee of that microgravity science experiments could succeed. However, the actual microgravity acceleration level of spacecraft is far from ideal due to various disturbances. Considering the situation, a cascade Active Disturbance Rejection Control (ADRC) method is proposed to improve the performance of vibration isolation and position...
Abnormal sensor signals may cause missed diagnosis in the fusion fault diagnosis system based on evidence theory. To diagnose the fault in time with abnormal sensor signals, fault-tolerance is required. An evidence redistribution method is proposed for the sensor fault-tolerance of fusion diagnosis system. The evidences directly calculated from sensor characteristic parameters are updated by an evidence...
