ANALYSIS AND PARAMETER SPECIFICATION OF THE TEMPERATURE CONTROL FOR A GAS PLASMA FACILITY.
Abstract
The thesis deals with a control system which is under development and construction. Each individual component is analyzed either by empirical or experimental means and a linearized transfer function is determined. These transfer functions are combined and simplified in a block diagram which is composed of an inner current regulation loop and an outer temperature regulation loop. Root locus analysis of the inner loop gives the necessary gain adjustments for the inner loop amplifiers and feedback elements. An average inner loop forward amplifier gain of about 1.0 gives a damping ratio of 0.8. Analog analysis of the basic system gives a forward amplifier gain average of 316 which produces a 4.4 second time to peak and an 11 second settling time. The average ramp error of about 1.76 is reduced to 1.4 with a lead compensator, which also reduces the time to peak to 1.6 seconds and the settling time to 3.0 seconds. A lag-lead compensator reduces the ramp error to about 0.14 and an ideal integral plus proportional compensator reduces the ramp error to zero. (Author)
