Smith Control Algorithm for Pure Time-Delay Systems

The Smith control algorithm for pure time-delay systems is presented with comprehensive simulation program listings and Simulink simulation modules. This control algorithm leverages the inherent characteristics of pure time-delay systems by calculating and adjusting controller parameters to achieve optimal system control. The implementation typically involves MATLAB scripting for parameter tuning and Simulink block diagrams for system modeling. Key components include the Smith predictor structure that compensates for time delays by using a parallel model of the process without delay. Through the provided simulation programs and Simulink modules, users can conduct performance evaluations by comparing system responses with and without the Smith compensator. The algorithm finds extensive engineering applications in various pure time-delay control scenarios such as chemical processes, temperature control systems, and network-based control systems, where it significantly improves stability and response characteristics by effectively handling transport delays.
