Intelligent Track Guide Control for Hearth Negative Pressure

Abstract

Hearth negative pressure is an important indicator of steam boiler. It's stable or not only directly affect the coal’s combustion efficiency but also an important parameter to ensure safety production. In the process of control, it has the characteristics of time-varying, nonlinear and coupling. In order to solve this problem, this thesis introduces Intelligent Track Guide Controller(ITGC) control scheme. ITGC principle is that transform the classic PID’s "objective control" to "process control". The ITGC simulation results were compared with PID, and simulation results show that: ITGC control scheme is better than the classics PID scheme in overshoot and settling time. Under a variety of conditions, the ITGC control scheme have an anti-interference ability. Applying ITGC to steam boiler’s hearth negative pressure control, it is fully capable of such a control system which have a multi-couplings and time variation.

State of the Art - Drones/Surface Platforms and Green Energy

“…-the main advantages of USV type platform According to the modes of operation we can classify the autonomous surface vehicles as autonomous, semi-autonomous and remote controlled. [12], [17], [18] The autonomous regime is also the most complex, in which the USV platform steers itself and manage options without human intervention according to the implemented code.…”
