Title: Enhanced Performance Controller Design for Stochastic Systems by Adding Extra State Estimation onto the Existing Closed Loop Control

Abstract

To enhance the performance of the tracking property , this paper presents a novel control algorithm for a class of linear dynamic stochastic systems with unmeasurable states, where the performance enhancement loop is established based on Kalman filter. Without changing the existing closed loop with the PI controller, the compensative controller is designed to minimize the variances of the tracking errors using the estimated states and the propagation of state variances. Moreover, the stability of the closed-loop systems has been analyzed in the mean-square sense. A simulated example is included to show the effectiveness of the presented control algorithm, where encouraging results have been obtained.

  • The Department of Energy's (DOE) Coal Fired Flow Facility (CFFF), located at the University of Tennessee Space Institute (UTSI) in Tullahoma, Tennessee, was designed to collect data necessary for the development of a commercial magnetohydrodynamic (MHD) system. The CFFF has an on-site coal processing system to convert raw coal to dry, finely pulverized coal suitable for dense-phase transport to the combustor. The coal processing system was designed primarily for use with Illinois No. 6, eastern type coal. However, DOE requires the use of Montana Rosebud, western coal as a fuel source for upcoming CFFF tests. Switching from Illinois No. 6more » to Montana Rosebud coal necessitated modification of the coal pulverizing and drying systems due to higher moisture content and volatility of the coal. A closed-loop inerted gas system, with a condenser to control moisture build-up, was selected to process the Rosebud coal. Nitrogen (N{sub 2}) is used to limit the oxygen (O{sub 2}) content of the recycled gas to below 5%. Descriptions of the process control equipment and logic are presented. Data on the resulting moisture and size distribution of the processed coal are reported.« less
