| Abstract: |
| Objective To choose a stable control strategy to achieve high-accuracy rotational control. Methods Adaptive fuzzy sliding mode control was chosen to control the rotation. This kind of control was applied with adaptive fuzzy system based on sliding mode control to approach and replace variable controller. Thus, it not only possessed stability and robustness, but also dramatically suppressed problematic chattering and smoothed the output of control. Results The tracking error of the method was under 0.01°, and the gradient of control output was under 40 000 step/s. Conclusion Under the capability of torquers, this method can drive sphere rotating accurately, less than 0.01°, as self-calibration and self-alignment needed. |
