Abstract:

The Pegasus actuator system was redesigned to accommodate the need for greater hinge torque. The decision to re-utilize, as much as possible, of the existing legacy actuator drive system is not necessarily a poor choice. However, one must understand that significantly increasing the performance requirements will stress all components in the (sub)system. Instantaneous currents associated with digital switching of power components can far exceed the steady-state values. When considering undertaking a significant redesign of a system or sub-system, extreme care must be taken to ensure that reutilization of existing components, i.e. motherboards, power supplies, cabling, etc., doesn't pose a greater risk than the initial cost and schedule impact of a complete (sub)system redesign.
