Abstract
The present invention discloses a combination missile target imitation flight test system, which includes a simulation development machine used in building a combination missile target flight control model, translating the simulation development machine into an executable code; an off-line simulation operation control model which records a rudder control signal and receives the rudder control signal from a simulation test host, comparing with the rudder control signal of the simulation operation model to judge the accuracy of a flight control software of the control system or the operation of a steering gear; the simulation test host which executes the executable code, sends the relevant track information of executing output to an interface box and sends the rudder control signal of an on-board control system transferred by the interface box to the simulation development machine; the interface box which is used for transferring the signals between the simulation test host and the on-board control system. The combination missile target imitation flight test system can perform a simulation test and a simulation experiment for the flight control system of multi-module and complex logic from model modification to physical simulation once, and is characterized by simple framework, low cost and high efficiency.
Description
technical field [0001] The invention belongs to the technical field of flight control and simulation, and in particular relates to a combined target missile flight imitation test system, which is used for performing simulation tests and simulation tests on a multi-module and complex logic target missile flight control system. Background technique [0002] With the development of technology and the application needs of diversified functions, the design of the target missile control system for simulating high-speed moving targets tends to be combined and serialized. The combined target missile control system has the characteristics of multi-module, combined, and complex logic. The traditional hardware-in-the-loop simulation system is mainly used for attitude control, its function is relatively single, and its cost is high, and its operating cost is high, so it is not suitable for the combined target missile control system. Therefore, it is urgent to develop a combination target...
