Abstract: A PID control apparatus and a method thereof are provided to minimize the configuration of circuit by utilizing a multi-rate technique. A PID(Proportional-Integrate-Derivative) control apparatus includes an error calculator(220), a PID calculator(230), a first sampler(240), and a controller(260). The error calculator outputs an error value of an output of a controlled object on a target value. The PID calculator obtains a proportional calculation value by performing a proportional calculation on the target value, obtains an integral calculation value by performing an integral calculation, obtains a differential calculation value by performing a differential calculation, and outputs a control value, which is obtained based on the proportional, integral, and differential calculations, to the controlled object. The first sampler samples the output of the controlled object on one target value and outputs the sampled value to the error calculator. The controller controls the PID calculator in order to output a control value by performing a PID calculation many times according to a sampling period of the first sampler.
