摘要：A real-time optimization control method is proposed to enhance engine thrust response and enlarge its maximum thrust during emergent flight. This real-time optimization control is model based, and the on-board engine predictive model is devised by a multi-input multi-output recursive reduced least squares support vector regression method. Two emergency engine control modes during engine emergent acceleration process, the overthrust mode and the faster response mode, are redesigned by specifying relative objective function with engine operation constraints. Namely, the overthrust mode is for getting much bigger maximum thrust, and the faster response mode is for obtaining faster engine response. In the initial engine acceleration stage, the two modes have the same objective function for fastest thrust response within necessary operation constraints. After that, the objective function varies to maximum thrust in the overthrust mode, whereas the faster response mode keeps the objective fo
