Linear actuators can be controlled and monitored by an Electronic Power Distribution System with no additional sensors or wiring. Laboratory and field test results are provided showing how common faults can be detected and annunciated, and potential faults can be detected before becoming hazardous. Results of these tests are extrapolated to other types of motors, such as pumps and fans.

The development of the microprocessor controlled power MOSFET switch, as a circuit protection device for aircraft electrical power systems, has led to significant improvements in packaging, performance and thermal efficiencies over traditional thermal/mechanical systems. The electronic circuit breaker (ECB) inherently provides multiple functions (protect, sense, diagnose, and control). Employing the ECB as a “live” switching element in the system for active control, provides for significant integration of functions, previously requiring separate LRUs, additional wiring and more power to operate. This paper proposes an optimized electrical power distribution via intelligent control of electronic circuit breakers to provide maximum integration of existing utility management functions (i.e. window heat, de-icing, thrust reversers, etc.), reduction in aircraft wiring, reduced system weight and complexity.
