摘要

摘要: 提出了一种燃气涡轮发动机加减速控制计划最优设计方法.该方法在发动机过渡态性能模型的基础上,变换描述发动机过渡态性能非线性模型中的自变量,最终实现过渡态控制计划的优化设计.以某型双轴混排涡扇发动机的加速过程为例,使用该方法规划得到了满足其加速过程限制的最优控制计划.将得到的控制计划代入发动机过渡态性能模型中进行验证.整体相对优化误差在0.1‰量级,表明该方法具有设计精度高、使用简单等特点.

Abstract: An optimum design method of acceleration and deceleration control schedule for gas turbine engine was proposed. Based on the engine transient state performance model, the transient state control schedule was optimized by changing the independent variables describing engine transient state performance of the nonlinear model in terms of the constraints. An example of the optimal acceleration control schedule for a dual axial mixed exhaust turbofan engine with different restrictions during accelaration was designed by using this method. The control schedule was verified by putting back into the engine transient state performance model. Overall relative optimize error is in order of 0.1‰. The results show enough accuracy and easy use of this method.
