Rhode Island Patent of the Month – January 2023

Electro Standards Laboratories Inc has recently been granted a patent for their design of a novel system which identifies gain values in advanced arresting gear (AAG) systems in aircrafts. The AAG system is responsible for stopping an aircraft safely during an emergency landing. The solution developed by Electro Standards Laboratories uses bins to identify gain values in the arrest controller of an aircraft arrestment system to better support AAG functioning.

The system involves maintaining a plurality of bins, each of which is associated with at least one gain value and covers an output range of the arrest controller function. The arrest controller function value is dynamically computed based on several input parameters, including the aircraft speed, port and starboard shaft positions, and failure/fault flags. The bin corresponding to the dynamically computed arrest controller function value is then identified.

Using weighting matrices, the system determines the controller design gain values that are picked to shape control loop transfer functions and dampen resonances in the aircraft arrestment system. The identified controller design gain values are then applied in the arrest controller to shape control loop transfer functions and dampen resonances, ensuring the safety of aircrafts during emergency landings.

This innovative system and method developed by Electro Standards Laboratories revolutionizes the way gain values in advanced arresting gear systems are identified, providing a safer and more efficient way to stop aircrafts during emergency landings.

Electro Standards Laboratories is a manufacturer of high quality, thoroughly tested electronic products. The company goes above and beyond manufacturing, bringing a team of R&D engineers and scientists to every project. This includes expertise in the development of electronics, digital signal processor based control, and coordination of multiple motor systems to brake large moving inertial mass. It’s this expertise that has culminated in the development of such a reliable AAG control system.
