- * @brief  Initialization function for the Q31 PID Control.
- * @param[in,out] *S points to an instance of the Q31 PID structure.
- * @param[in]     resetStateFlag  flag to reset the state. 0 = no change in state 1 = reset the state.
- * @return none.
- * \par Description:
- * \par
- * The <code>resetStateFlag</code> specifies whether to set state to zero or not. \n
- * The function computes the structure fields: <code>A0</code>, <code>A1</code> <code>A2</code>
- * using the proportional gain( \c Kp), integral gain( \c Ki) and derivative gain( \c Kd)
- * also sets the state variables to all zeros.
