Aiming at the uncertainty of model parameters and dominate time delay of the controlled object in feed water system of boiler, combined with improved Smith predictor control method and fuzzy immune PID control method, improved Smith predicting controller based on fuzzy immune is designed. Fuzzy Immune PID controller can self-tune parameters, and has adaptive capacity to the diversification of c...

In the networked control system with random time delay in forward and feedback channels, a kind of controller based on Smith compensator and signal neuron incomplete differential forward PID is presented. First, using root locus method and simulink simulation software, the influences of network’s time delay on the system stability and dynamic performance are analyzed. Then, combined with incomp...

In this paper, we propose a data-driven approach to the Smith compensator for the simultaneous attainment of a controller and a mathematical model of linear time-delay SISO systems. Under the situation in which we do not know a mathematical model of a plant, the proposed method here enables us to obtain the optimal Smith compensator for the desired tracking property based on the direct utilizat...

Solution of Large-Scale Lyapunov Equations via the Block Modified Smith Method by John Sabino Balanced truncation is an attractive method for reducing the dimension of mediumscale dynamical systems. Research in recent years has brought approximate balanced truncation to the large-scale setting. At the heart of this technique are alternating direction implicit (ADI) methods for solving large Lya...
