摘　　要：In order to realize direct thrust control instead of traditional sensor-based control for aero-engines,it is indispensable to design a thrust estimator with high accuracy,so a scheme for thrust estimator design based on the least square support vector regression machine is proposed to solve this problem. Furthermore,numerical simulations confirm the effectiveness of our presented scheme. During the process of estimator design,a wrapper criterion that can not only reduce the computational complexity but also enhance the generalization performance is proposed to select variables as input variables for estimator.In order to realize direct thrust control instead of traditional sensor-based control for aero-engines, it is indispensable to design a thrust estimator with high accuracy, so a scheme for thrust estimator design based on the least square support vector regression machine is proposed to solve this problem.
