本文研究综合火力/飞行控制系统的设计问题,在国内首次提出了一套设计空——空IFFC系统的比较系统有效的方法。本文成功地建立了IFFC系统设计中所涉及的诸子系统的模型并根据设计需要进行了简化,从而得到了一组比较合理的,具有纵侧分离性质的线性模型。为了使所设计的系统在各种限制下具有良好的动态性能,同时也为了控制规律设计与实现的方便,本文根据模型特点,提出了控制系统抗干扰设计的“强可控/弱可控”子系统分离设计的方法,这一方法是适用于一类线性系统设计较为一般的方法,它在IFFC控制器设计中的应用大大简化了调参规律并较好地解决了控制大小限制与Robust性的矛盾。整个设计对Robust性给予了充分的重视,文中给出了线性系统在非线性时变摄动下保持稳定的一个摄动界,利用这一结果研究了系统的时变摄动下的Robust性。仿真结果表明本文提出的方法设计的系统具有良好的Robust性和满意的时域特性。
In this paper, the design of integrated firepower / flight control system is studied in this paper. For the first time, a systematic and effective method for designing air-air IFFC system is proposed. In this paper, we have successfully established the models of the subsystems involved in the design of IFFC system and simplified the design according to the requirements of the design. Thus, a set of rational linear models with vertical separation properties are obtained. In order to make the designed system have good dynamic performance under various restrictions and at the same time, in order to control the design and implementation of the law, according to the characteristics of the model, this paper presents a “strong controllable / weakly controllable” This method is suitable for a class of linear system design more general method, its application in the design of the IFFC controller greatly simplifies the law of reference and solves the problem of control size and Robust Contradictions. Robust design is given full consideration in the whole design. In this paper, a perturbed bound of the linear system which is stable under nonlinear time-varying perturbation is given. Robustness of the system under time-varying perturbation is studied by using this result. The simulation results show that the system proposed by the proposed method has good Robust and satisfactory time-domain characteristics.
