Use of Filtered Smith Predictor in Dmc
نویسندگان
چکیده
The use of DMC in industry is very extended. Traditionally, its formulation has been based on the Dynamic Matrix model, obtained from the step response of the system. This work shows an alternative formulation that is based on a transfer function model, and divides the DMC into two parts: controller and predictor. This allows the easy substitution of one for another. Thus, SPDMC is obtained by substituting the predictor for the Smith predictor (SP) this being equivalent to DMC. The SPDMC properties have been made more robust by adding filters.

A Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes
This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...
متن کاملNeural-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...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...
متن کاملImprovements on the Filtered Smith Predictor using the Clegg Integrator
This paper presents a non-linear control scheme to deal with dead-time (DT) processes where small rise times are required. The control scheme is based on the combination of two strategies appeared in the literature to deal with DT processes, the Filtered Smith Predictor (FSP), which is a Smith Predictor (SP) including a filter to improve the robustness, and the PI+CI, a PI with a partial reset ...
