The article deals with the aspects of occurring the effect of structural and parametric non-stationary states of various kinds in the models of feeding devices (FD), the latter is considered as the part of a continuous-type mixture-producing aggregate. Relevant features of such an effect are revealed and discussed. In particular, different types of transient modes that occur in the feeding devices under increasing or decreasing the load applied to the intake part of feeders are introduced and described. To demonstrate the complexity of feeding devices models, the distribution of numbers and types of poles for models of different FD-unit configurations have been submitted here. Also we operate with concepts of the so-called autonomously sporadic and forced-modal transient processes, and their images in the forms of 1D-signals and time-frequency distributions are brought in. Finally, the procedures of calculating the modal controller parameters, i.e. the full state feedback matrix, are given in detail.
