Neural-Smith Predictor Method for Improvement of Networked Control Systems

Networked control systems (NCSs) are distributed control systems in which the nodes, including controllers, sensors, actuators, and plants are connected by a digital communication network such as the Internet. One of the most critical challenges in networked control systems is the stochastic time delay of arriving data packets in the communication network among the nodes. Using the Smith predic...

Parallel compensator versus Smith predictor for control of the plants with delay

In the paper the parallel compensator considered in [1] is applied to control of the plants with delay and compared with Smith predictor. It is noted that Smith predictor removes only the delay, while the parallel compensator also changes the dynamics of the replacement plant; the latter may be in some degree of freedom shaped by the designer. Owing to this the transients of the system with par...

Simulation of Networked Control System based on Smith Compensator and Single Neuron Incomplete Differential Forward PID

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...

Modified Internal Model Control for Non-square Systems Based on Smith Delay Compensator Control

A modified internal model control method based on static decoupling for non-square processes with right half plant zeros and multiple time delays is proposed. The coupled problems of non-square processes are solved by used pseudo-inverse of steady-state gain matrix. Internal model controller is also applied to Smith delay compensator directly by using equivalence between internal model control ...
