    Lumpkin and Stewart County Marker, Lumpkin, GA. This marker is located on the Stewart County Courthouse, in Lumpkin, Georgia. The text reads as : LUMPKIN AND STEWART COUNTY Lumpkin, named for Wilson Lumpkin, Governor, Congressman and Senator, first the County Seat of Randolph County, became the Seat of Government of Stewart County when that county was consti-tuted from Randolph December 23, 1830. On a hill between two Indian trails to Florida, the first Courthouse, built of logs in August 1830, was used as a blockhouse in the Indian outbreak in 1.A two story frame Courthouse stood until 1895, when one of brick, cornerstone laid by Masons, was built and repaired and rebuilt in 1922 after damage by fire. Stewart County was named for Brig. Gen. Daniel Stewart, Revolution-ary soldier brevetted for bravery in Georgia’s Indian Wars. In this County are Providence Canyons, sites of fort McCreary, Fort Jones, Oconee Village, Battle of Shepherd’s Plantation Indian Mounds and Roanoke. First officers of Stewart County were: William Duncan, Needham R. Bryan, Henry Audulph, Judges of Inferior Court; Sampson L. Lampkin, Surveyor; Edward Sturdivant, Coroner; Thomas M. Dennis, Clerk Inferior Court; Thomas R. Mangham, Clerk Superior Court; Jonathan F. Bridges, Sheriff; James S. Lunsford, Tax Receiver; Cullen Roberts, Tax Collector.

    Stewart County Academy and Masonic Building Marker Lumpkin GA. It is located opposite the courthouse in Lumpkin, Stewart County ,GA. The text reads as: This building was erected in 1831 in NW Lumpkin to house the `Stewart County Academy,` the first academy in the county. In 1842, it became the `Lumpkin Independent Academy` for boys only, owned by local stockholders. In 1841, the first Sunday School, interdenominational, was organized in the building. Purchased in 1885 by E.M. Sheram, the building was moved to this corner and used as a carriage factory, general store, fire station, and gasoline station. The second floor has been used continuously since 1885 as a lodge room by Cross Chapter No. 173 Masons, organized as Cross Lodge No. 12, Nov. 8, 1838.

    As is well known, the metal annealing process has the characteristics of heat concentration and rapid heating. Traditional vacuum annealing furnaces use PID control method, which has problems such as high temperature fluctuation, large overshoot, and long response time during the heating and heating process. Based on this situation, some domestic scholars have adopted fuzzy PID control algorithm in the temperature control of vacuum annealing furnaces. Due to the fact that fuzzy rules are formulated through a large amount of on-site temperature data and experience summary, there is a certain degree of subjectivity, which cannot ensure that each rule is optimal. In response to this drawback, the author combined the technical parameters of vacuum annealing furnace equipment, The fuzzy PID temperature control of the vacuum annealing furnace is optimized using genetic algorithm. Through simulation and comparative analysis, it is concluded that the design of the fuzzy PID vacuum annealing furnace temperature control system based on GA optimization is superior to fuzzy PID and traditional PID control in terms of temperature accuracy, rise time, and overshoot control. Finally, it was verified through offline experiments that the fuzzy PID temperature control system based on GA optimization meets the annealing temperature requirements of metal workpieces and can be applied to the temperature control system of vacuum annealing furnaces.</div
