Research of efficiency of use of systems of the guaranteeing management for regulation of parameters of technological process of cultivation of yeast

The article examines the feasibility of using systems management guarantees for the calculation of control actions to control the process of growing the yeast. This article contains a brief description of the process of growing yeast, the main technological equipment and the principles of process control. In the conduct of the process of growing the yeast is necessary to maintain a certain temperature, which ensures their optimum growth. To study the effectiveness of using systems guarantee for controlling the temperature of the culture medium was used by digital simulation model was developed object management, taking into account the static and dynamic characteristics of a real object. System modeling was carried out taking into account the influence of the coordinate and parametric perturbations. The results of the simulation system ensures control was compared with similar results of modeling the automatic control system using a proportional-integral-differential control algorithm. As a general criterion for the effectiveness of automatic control systems were used the following criteria: the number of intersections controlled variable maximum temperature limit values and integrated modular quality criterion. Experiments have shown that the use of control systems guarantee limit values are violated less often, however, this may deteriorate the quality criterion value of the integral system characterizes the distance schedule optimally controlled variable from the definition of sustainable setpoint adjusted. Application of guaranteeing management is a promising direction in the development of control systems for the test process.
