<P>PROBLEM TO BE SOLVED: To provide a control apparatus which prevents continuity of control from being deteriorated when switching calculation means. <P>SOLUTION: A control apparatus comprises: first calculation means that performs calculation for equipment control based on an input signal; second calculation means that performs the same calculation; determination means that determines whether or not the first calculation means functions properly; selection means that performs switching to output the result of the calculation performed by the first calculation means as the control signal when the first calculation means is determined as functioning properly by the determination means, and the result of the calculation performed by the second calculation means as the control signal when the first calculation means is determined as not functioning properly; and storage means that stores the difference between the results of the calculations performed for the same input signal by the first calculation means and the second calculation means at a predetermined timing. When the result of the calculation by the second calculation means is output as the control signal, the result of the calculation by the second calculation means is compensated by using the difference stored by the storage means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
