The authors consider a problem of choosing optimal parameters for a hydraulic drive with a discrete control output link by the example of a hydraulic fan of a heavy-duty vehicle’s engine cooling system. The objective function was selected in accordance with the efficiency criterion of the hydrostatic power drive. Limits of variable parameters’ values were set to reflect the work of the hydraulic drive in the specified system. Results of the application of genetic and modified genetic algorithms for determining parameters of the hydraulic drive were described in this article. The obtained results were compared with the results based on the LPτ- search of hydraulic parameters, optimal by two criteria. Academic novelty of this article consists in consideration of different approaches to the problem of interactive design of technical systems with discrete controls which is composed of commercially available standard hydraulic units.
