A linear model of the object is considered having 2 channels for input and 1 channel for output. The problem was that it was necessary to achieve certain quality indicators of the output scalar process when controlling two input influences. Such a task is not ordinary, an example of such objects can be a manipulator with two controls or for example an AC motor, where one input is the current along the d axis, and the second along the q axis. To solve the problem, a polynomial synthesis method was used. The object was presented in the form of a left polynomial decomposition, and the regulator of the right. When solving this problem, free regulator parameters may appear that allow us to understand what possibilities the regulator presents to us.
