simpleDeadband#
Executive Summary#
This method applies a two-level deadbanding logic (according to the current average simple compared with the set threshold) and decides whether control should be switched ON/OFF or not.
Message Connection Descriptions#
The following table lists all the module input and output messages. The module msg connection is set by the user from python. The msg type contains a link to the message structure definition, while the description provides information on what this message is used for.

Class SimpleDeadband#
-
class SimpleDeadband : public SysModel#
Top level structure for the sub-module routines.
Public Functions
-
void reset(uint64_t callTime) override#
This method performs a complete reset of the module. Local module variables that retain time varying states between function calls are reset to their default values.
- Parameters:
callTime – The clock time at which the function was called (nanoseconds)
- Returns:
void
-
void updateState(uint64_t callTime) override#
This method parses the input data, checks if the deadband needs to be applied and outputs the guidance command with simples either zeroed (control OFF) or left unchanged (control ON)
- Parameters:
callTime – The clock time at which the function was called (nanoseconds)
- Returns:
void
-
void applyDBLogic_simpleDeadband()#
This method applies a two-level deadbanding logic (according to the current average simple compared with the set threshold) and decides whether control should be switched ON/OFF or not.
- Returns:
void
