Apparatus and method for proportional-integral-derivative control |
摘要 |
<p>A PID controlling apparatus and method for providing a control value to a control object according to the difference between an output value of the control object and a target value are provided, in which an error calculator outputs an error value between the target value and the output value of the control object, a PID operator calculates a proportional value, an integral value, and a derivative value of the error value, calculates the control value using the proportional value, the integral value, and the derivative value, and outputs the control value to the control object, a first sampler samples the output value of the control object a plurality of times with respect to the target value and outputs a sampled output value, and a controller controls the PID operator to repeat a PID operation and output the control value according to a sampling period of the first sampler.
