Redundant Electromechanical Actuators for Aerospace: Design Principles and Equalisation Strategies

The rapid move toward all electric and autonomous aerospace systems has increased the demand for actuation technologies capable of delivering safe and reliable performance under fault conditions, sensor drift, and mechanical mismatch. This webinar provides a detailed and practical overview of redundant electromechanical actuators (EMAs) used in aerospace flight control applications, highlighting their relevance to modern robotics and advanced mechatronic systems.

The session introduces the behaviour and design considerations of torque summed and velocity summed multi lane architectures and explains how force equalisation and lane equalisation can reduce torque disparity, suppress force fight, and maintain accurate motion control under non ideal conditions such as drift or component variation. The webinar also presents the role of Monitoring, Voting, and Averaging Devices (MVADs) and quantile-based threshold setting techniques, illustrating how these methods support improved fault detection, isolation, and overall system resilience.

The webinar also highlights the application of Monte Carlo based threshold setting methods for dependable monitoring. These techniques generate large scale probabilistic simulations that capture sensor drift, torque variation, and lane mismatch across a wide range of operating conditions. By analysing the resulting probability distributions, it becomes possible to define robust thresholds that minimise false alarms while ensuring timely detection of emerging faults. This provides a data driven basis for screening limits within MVADs and strengthens the development of reliable, high integrity actuation in demanding aerospace environments.

This webinar is suitable for researchers, engineers, and practitioners working in aerospace, robotics, mechatronics, and autonomous systems who aim to enhance system dependability and performance in modern electromechanical actuation systems.
