Abstract
A method and system for operating an inlet door of an auxiliary power unit are provided. A control signal comprising at least one inlet door command is output. In response to the at least one inlet door command, at least one feedback signal is received and compared to the at least one inlet door command. If the at least one received feedback signal matches the at least one expected feedback signal, operation of the auxiliary power unit is allowed. Otherwise, operation of the auxiliary power unit is inhibited.
Claims15
A method for operating an inlet door of an auxiliary power unit, the method comprising:
- outputting a control signal comprising at least one inlet door command;
- receiving, in response to the at least one inlet door command, at least one feedback signal;
- comparing the at least one received feedback signal to the at least one inlet door command;
- if the at least one received feedback signal matches the at least one inlet door command, allowing operation of the auxiliary power unit;
- and
- inhibiting operation of the auxiliary power unit otherwise.
A system for controlling an inlet door of an auxiliary power unit, the system comprising:
- a memory;
- and
- a processing unit coupled to the memory and configured to:
- output a control signal comprising at least one inlet door command;
- receive, in response to the at least one inlet door command, at least one feedback signal;
- compare the at least one received feedback signal to the at least one inlet door command;
- if the at least one received feedback signal matches the at least one inlet door command, allow operation of the auxiliary power unit;
- and
- inhibit operation of the auxiliary power unit otherwise.
A non-transitory computer readable medium having stored thereon program code executable by a processor for:
- outputting a control signal comprising at least one inlet door command;
- receiving, in response to the at least one inlet door command, at least one feedback signal;
- comparing the at least one received feedback signal to the at least one inlet door command;
- if the at least one received feedback signal matches the at least one inlet door command, allowing operation of the auxiliary power unit;
- and
- inhibiting operation of the auxiliary power unit otherwise.
