Detailed Description

This class implements the Fuzzy logic controller as defined by the SWA-1330 GM6000 Fuzzy Logic Temperature Control document.

The interface should be called on periodic basis.

The interface receives its 'configuration' via model points

Inputs are (all values must have the same degree units): Current Temperature Current Setpoint

Outputs: Value to change/adjust the current capacity 'output signal'

Member Function Documentation

calcChange()

int32_t Ajax::Heating::Flc::Api::calcChange ( int32_t  currentTemp, int32_t  setpoint  )

noexcept

This method should be called on a fixed periodic basis to calculate the fuzzy output.

The output is change (to increase/decrease) the current request output capacity

defuzz()

int32_t Ajax::Heating::Flc::Api::defuzz ( const int32_t  outVector[AJAX_HEATING_FLC_CONFIG_NUM_MEMBER_SETS] )

protectednoexcept

Helper method the defuzzifys the output vector.

fuzzify()

void Ajax::Heating::Flc::Api::fuzzify ( int32_t  inValue, int32_t  fuzzyOut[AJAX_HEATING_FLC_CONFIG_NUM_MEMBER_SETS]  )

protectednoexcept

Helper method to fuzzify an input value.

runInference()

void Ajax::Heating::Flc::Api::runInference ( const int32_t  m1Vector[AJAX_HEATING_FLC_CONFIG_NUM_MEMBER_SETS], const int32_t  m2Vector[AJAX_HEATING_FLC_CONFIG_NUM_MEMBER_SETS], int32_t  outVector[AJAX_HEATING_FLC_CONFIG_NUM_MEMBER_SETS]  )

protectednoexcept

Helper that executes the inference rules.

start()

bool Ajax::Heating::Flc::Api::start ( )

noexcept

This method is used to initialize/reset the Controller.

It should be called once, before calls to calcChange().

Return true if successful; else false is returned

stop()

void Ajax::Heating::Flc::Api::stop ( )

noexcept

This method is used to stop the controller.

Once stopped, the controller can be restarted by calling start().
