Integrated guidance and control using model predictive control against a maneuvering target is proposed. Equations of motion for terminal homing are developed with the consideration of short-period dynamics as well as actuator dynamics of a missile. The convex optimization problem is solved considering inequality constraints that consist of acceleration and look angle limits. A discrete-time extended Kalman filter is used to estimate the position of the target with a look angle as a measurement. This is utilized to form a flight-path angle of the target, and polynomial fitting is applied for prediction. Numerical simulation including a Monte Carlo simulation is performed to verify the performance of the proposed algorithm.
提出了一种针对机动目标的基于模型预测控制的综合制导与控制方法。考虑到导弹的短周期动力学以及舵机动力学，建立了末制导运动方程。在考虑由加速度和视线角限制组成的不等式约束的情况下求解凸优化问题。采用离散时间扩展卡尔曼滤波器，以视线角作为测量值来估计目标位置。利用该估计值形成目标的飞行路径角，并应用多项式拟合进行预测。进行了包括蒙特卡罗模拟在内的数值仿真，以验证所提算法的性能。
