A two-degree-of-freedom control scheme is proposed for enhanced control performance of integrating and unstable processes with time delay. The two controllers in the scheme are well placed to tune from the setpoint and disturbance. The design steps of these two controllers are independent. The H2 optimal control method is used to design the set-point tracking controller and an optimal internal model...
Proper control of the wood-drying kiln is crucial to ensure the satisfactory quality of dried wood and in minimizing drying time and energy. This paper investigates the development and evaluation of a robust control system for a wood drying kiln process incorporating variable structure control (VSC) such that the moisture content of lumber will reach and be stabilized at the desired set point. A description...
In this paper, we address an end-to-end congestion control algorithm for the available-bit-rate (ABR) traffic in high speed asynchronous-transfer-mode (ATM) networks. A fuzzy immune PID controller is designed to overcome the adverse effect on ATM network caused by uncertainties such as the number of users, the available-bit-rate bandwidth, and the transmission propagation delays. Further, an algorithm...
PID neural network controller design for Sharif University of Technology (SUT) building energy management system (BEMS) is addressed in this paper. The most important characteristics of process systems are time delay with model uncertainties. Artificial neural networks can perform adaptive controller properties through learning processes. PID neural network has the advantage of both conventional PID...
