Industrial Automatic Control Systems and Controllers Annotation << Back Automatic Controllers and Devices with Enhanced Functionality A.E. Mertsalov А.А. Govorov To create a more sophisticated control systems of various technological processes and offered regulators and devices with advanced features: bumpless switching regulator when switching from remote (manual) mode to automatic control and vice versa, as well as with external reference with the internal supervisory control; limiting the individual components of the controller output at the upper and lower limits, and protect them from saturation. Application of the proposed controllers and devices in the current system of technological parameters can signifi cantly improve the quality of our products and to obtain additional technical and economic effect. Keywords: PI and PID controllers; device; enhanced functionality; bumpless switching regulator; transition from external to internal job; Supervisory control; the output correction signal; limit control signals; protection from saturation of the regulator; protection devices saturation precession and differentiation; process synthesis and methanol distillation.
