System two-position control of liquid level in industrial tanks
National Research Tomsk Polytechnic University, 634050 Tomsk, Russia
Design of the automatic liquid level control was performed for the tank rectangular type with the presence of self-regulation. Were found settings of two-position automatic controller with a zone of ambiguity with symmetric static characteristic. Settings meet the specified requirements for the automatic control system. Opportunities and stability of self-oscillations of the controlled variable were assessed by the method of harmonic balance. Was created a virtual model of single-circuit system two-position control of liquid level and estimates the quality of regulation.
