The method of synthesis of digital nonlinear control with an electro-hydraulic drive is proposed. It is based on the combination of the method of synthesis of the digital part of the system with a continuous prototype and the expert approach. At the first stage, the continuous regulator is synthesized based on known techniques. At the second stage, a transition to the digital regulator is performed with the help of the z -transformation and the difference equation is determined. The sampling period is selected at a frequency greater than the frequency that determines the bandwidth of the continuous electrohydraulic drive control system (its degree is determined by way of further modeling and evaluation of the results obtained). In the third stage, the modeling for digital control options with selected sampling frequencies and recalculated parameter values of the regulators is carried out. The example of the synthesis of a digital regulator with the use of electro-hydraulic control system is given.
