| Abstract: | A method of resistance furnace temperature control using phase-locked loops (PLL) technique is described. It is a cascade control system consisting of an inside loop and an outsideloop: the inside loop of the control system uses a PLL as stability adjustment, the outside loopuses single-chip-microcomputer-bas digital control in order to improve system charactristics.the principle, system architecture, software design and the initial test results in 300 W resistance furnace temperature control is briefly described. |
