| 摘要: |
| 为了解决航空发动机约束预测控制器的设计问题,针对状态空间模型,经推导将无约束的二次型性能指标式转换成有约束的二次型性能指标式,采用二次规划方法计算出有约束预测控制量。按无约束和有约束,模型匹配和不匹配分别对某型发动机进行仿真计算,取得了不同约束条件对发动机动态性能和静态性能的影响情况,并举例将仿真数据转换成物理数据。仿真结果符合物理规律,计算方法得到验证。 |

| Abstract: |
| In order to resolve the design problem of constrained predictive controller of aero-engine,the unconstrained quadratic model performance index formula is changed to constrained quadratic model performance index formula based on the state space model of aero-engine,and the constrained predictive control variables are calculated by adopting quadratic programming method.Calculation and simulation of dynamic and static performance of some aero-engine are performed respectively according to the unconstrained and constrained condition on model matched and non-matched.The data of dynamic and static performance of the aero-engine are obtained in different constrained conditions.The study shows that the calculating results accord with physics rule and the calculating method is validated. |
