Design and Evaluation of Dual-Resolver Emulation for Control System Verification in Aerospace Actuation Applications

Unlike much of industrial power electronics, aerospace actuation comes with the requirement of additional design rigor and exhaustive validation and verification of firmware and hardware. The elevated degree of design assurance stems from the safety criticality of the application. Much of the design - power electronics, firmware, and mechanical subsystems - needs to be done in parallel. The integrity with which a full aerospace application control system can be verified under dynamic operating conditions while the rest of the system is being designed or constructed can be improved by precise emulation of critical sensors such as shaft resolver. In this paper, we propose and evaluate a low-cost dual-resolver emulator for the control of aircraft doors.
