Abstract

PURPOSE:To improve the tracking performance without complicating the control arithmetic operation by entering a new output period even on the way of the output period if a setting value revision of the control system or the revision of the proportional band takes place and using the new output so as to apply the control. CONSTITUTION:The control arithmetic block 1 calculate according to a prescribed arithmetic equation. The output rate yn is converted into a control pulse pn of a prescribed ON/OFF duty ratio in the pulse arithmetic operation block 5 and outputted to the controlled system 3. The arithmetic operation timing in the block 5 is controlled by an output change discrimination block 6. When the block 6 discriminates the necessity of the revision in the output timing, an output revision command signal is outputted from the block 6. Then the block 5 completes the output period prevailing at present and starts a new output period in the blocks 1, 5 based on the actually measured value in the timing to output a pulse rate calculated newly.
