  • Publication number: 20250106950
    Abstract: Provided is a serial-type planar heat-generating heater and a manufacturing method thereof. In particular, the present invention relates to a serial-type planar heat-generating heater, which is capable of maximizing the effect of heating by minimizing dead zones in which heat is not generated, achieving a maximum power output in a limited area, unlike in a parallel-type heater, and achieving high temperature uniformity in all of heat-generating surfaces of the planar heat-generating heater, is easy to design to control heating performance, and may be manufactured at low costs; and a manufacturing method thereof.

  • Patent number: 7979143
    Abstract: 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.
