- * \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.
