Flight control law one-dimensional interpolation table design method

Abstract

The invention belongs to the field of flight control law design, and particularly relates to a flight control law one-dimensional interpolation table design method. The method includes the following steps: 1, designing an interface of a flight control law one-dimensional interpolation table; 2, initializing the flight control law one-dimensional interpolation table; 3, performing periodic operation design of the flight control law one-dimensional interpolation table; and 4, according to the row array and the interpolation data array interval endpoint value, solving the current output value of the one-dimensional interpolation table by a straight line fitting method. According to the flight control law one-dimensional interpolation table design method, a judgment mechanism based on a previous frame memory function is used, the binary search frequency is reduced, the average operation time of the control law on a target machine is shortened, and then the overtime risk of a flight control system is reduced; and besides, a universal thought is adopted for positioning and searching, the method is a lightweight solution, and operation is efficient and stable. The method has universality and can be used as a template to be applied to control law design of other projects.

Description

technical field [0001] The application belongs to the field of flight control law design, in particular to a method for designing a flight control law one-dimensional interpolation table. Background technique [0002] The flight control law is one of the cores of the aircraft flight control system, and its quality directly affects the flight safety and flight experience of the aircraft. The flight control system is a strong real-time system, so the periodic tasks scheduled and executed by the flight control system software are also strong real-time tasks, which must be executed within the specified time. If the periodic tasks are not scheduled and completed within the period time during software execution, it will cause immeasurable losses to the system. The one-dimensional interpolation table is one of the basic calculation modules of the flight control law, but the commonly used one-dimensional interpolation module involves huge data, and there are outstanding problems of...
