Abstract:
A method for collecting information required for Bode plot creation of a UAV (Unmanned Aerial Vehicle) autopilot system is provided. The method comprises: creating a Bode plot generation input signal: adding the Bode plot generation input signal to control inputs; collecting data from multiple points within the control system; calculating magnitude and phase at the multiple points using the data collected; recording the magnitude and phase for the multiple points in a datalog; comparing the magnitude and phase for the multiple points to calculate the gain and phase margins for open loop responses in the control system; creating a Bode plot for at least one of the following: i) a closed loop response of the attitude and/or rate loops, ii) an open loop response of the attitude and/or rate loops and iii) a response of the UAV; and outputting the Bode plot.
Abstract:
An electronic flight test card for testing a UAV (Unmanned Aerial Vehicle) design is provided. The flight test card comprises: a module comprising a list of tests to be performed, each test linked to a requirement for a system or subsystem of the UAV; an interface for communicating with the UAV; a storage medium with a data log for storing the test results captured by the interface; a display module for displaying test items; and an output for exporting the data log to a configuration system.
Abstract:
A computer-implemented method and system of designing failure modes of a product is provided. The method comprises: decomposing systems of the product into subsystems based on information stored in a database; receiving through a user interface a failure mode for at least one of the subsystems; adding at least one requirement to the subsystem to address the failure mode; implementing the at least one requirement; validating the implementation at a subsystem level, a system level and a product level; and outputting results of the validating to a configuration system.
