The invention provides a control law parameter design method for a flight control system, and the method comprises the steps: constructing an aircraft aerodynamic model, solving the aircraft aerodynamic model, and obtaining a plurality of groups of flight dynamics parameters related to the aerodynamic force and thrust of an aircraft, calculating a control parameter group in each flight state by using a feature structure configuration or dynamic inverse method according to the flight dynamics parameters, and determining a maximum value and a minimum value in the control parameter group; and forming a control parameter band based on the maximum value control parameter, the minimum value control parameter and the standard state control parameter in the control parameter group in each flight state, and drawing a simplified control parameter curve according to the control parameter band, thereby completing the determination of the control parameters of the flight control system. According to the method, the dynamic inverse and feature structure configuration theory is applied to the control law parameter design of the flight control system, so that the control parameters can be quickly obtained, and the sensor measurement limitation and the computer operational capability limitation can be reduced to a certain extent.
Description
technical field [0001] The present application belongs to the technical field of flight control, and in particular relates to a control law parameter design method of a flight control system. Background technique [0002] For example, with the use of new control surfaces and thrust vectoring technologies, the flight control system becomes more and more complex, and the control law design of the flight control system using traditional control technologies and theories becomes more complicated and the design efficiency decreases. Therefore How to apply the latest control theory to flight control has always been the focus of flight control research. Among them, the characteristic structure configuration and dynamic inverse method are widely studied and applied in the field of flight control. These two methods can quickly design the control law parameters, but affected by the sensor measurement technology, the measurement results include factors such as noise and sensor characte...
