Abstract

The invention belongs to the aircraft control system field, and provides a control rule verification platform and a control rule verification method capable of configuring redundancy level. The control rule verification platform comprises a four-redundancy real-time simulation node, a software loading/system testing computer, an Ethernet network and a reflective memory network, wherein the four-redundancy real-time simulation node is composed of four embedded computers identical in function, performance, interface and composition, and runs a V*Work real-time operation system, data cross transmission is performed among the computers through a CCDL (cross channel data link), the CCDL further comprises a synchronous cable used for clock synchronization management among simulation nodes, and the four redundancy real-time simulation node runs a flight control system algorithm, and inputs and outputs data through a physical I/O (input/output) interface.

Description

technical field [0001] The invention belongs to the field of aircraft control systems and is suitable for verification of control law algorithms of aircraft flight control systems and redundancy control systems in other high-safety and high-reliability fields. Background technique [0002] The control law is the core logic algorithm to realize the control function of the control system. The reliable operation of the flight control system is the guarantee of flight safety, and its slight failure may lead to catastrophic consequences for the aircraft. In order to improve the reliability of the flight control system, under the premise that the basic reliability of the components is certain, its core components such as sensors, computers, actuators, etc. have adopted redundancy technology. At present, the early verification work in the control law design stage is the algorithm simulation carried out by all-digital means. The verification goal is only limited to the correctness ...
