摘要 针对使用推力矢量控制的航天器,建立了游动发动机的数学模型,在分析了游动发动机摆角约束的基础上,提出了推力矢量控制分配问题.将该控制分配问题转化成以力矩误差最小和对变轨推力影响最小作为优化目标的多目标优化问题,引入序列二次规划进行求解,得到一种新的控制分配方法.仿真结果表明,该方法能够准确实现期望目标,验证了所提出的控制分配方法的可行性和有效性. This paper establishes the model of vernier thrusters for spacecrafts using thrust vector control. The thrust vector control allocation algorithm is proposed based on the analysis of the constraints of vernier thrusters. The sequential quadratic programming-based thrust vector control allocation algorithm can minimize the torque errors and thrust errors. Numerical simulation shows that this method can be used to obtain preferable allocation results and the control allocation method is feasible and effective .
