Abstract A model of a two-step anaerobic fermentation in a bioreactor-mixer, whose mathematical description is a system of nonlinear mathematical equations, is discussed. The purpose is to design an algorithm of an energy-saving control relying on the principles of nonlinear adaptation on target manifolds with an attractive property, which are referred to as invariants or invariable laws of the target system behavior for the object under study. A necessary preliminary step is the formalization of possible target invariants in the form of prescribed (desired) laws of the controlled object behavior. An example is given of designing a vector regulator with a compensation of random disturbances over the control channel in a system of anaerobic biological waste water treatment.

Direct control of hydraulic cylinders - without use of control valve, represents a newer concept of energy-saving control of cylinders, without damping losses. In order to study this type of drive, it is necessary to design and manufacture a compact model of such device to study the control concepts and to check the operation of the system. We will study the existing implementations of such drives and create our own direct driven servo-hydraulic actuator (hereinafter DD SHA), with which we will move different loads. A servomotor must be attached to a suiTable hydrostatic unit (pump-motor). All the missing components need to be designed and manufactured for completed hydraulic circuit.
