Intelligent controller based on pattern recognition

Considering different types of time-varying lag system, control strategy is determined by recognition of transient characteristics of responses and cooperation with expert system, forming the basic idea of intelligent controller design. Based on the dynamic response mode of the controlled object, multi control mode was applied in control law, which can solve the oscillation problems appeared in common control system during pure lag link and improve the robustness of the control system. The application of intelligent temperature controller based on the pattern recognition in the same category of controlled objects requires no specific parameters and mathematical model of the controlled objects, but can bring a stable increase of manipulated variable, quick response, small overshoot, and no steady-state error, enabling it appropriate for different types of controlled objects and achieving perfect control effect.
