    Predictive neural network controller for hydrostatic transmission control
    (Wydawnictwa AGH, 2008) Nawrocka, Agata; Kwaśniewski, Janusz
    In this paper predictive neural network controller is applied to control rotational speed of hydraulic engine hydrostatic transmission. It describes the functional structure and design principle of predictive neural network controller. This predictive neural network control method provides control linear and nonlinear systems. In this case feed forward network with one hidden layer was used. The control objective is to minimize a control cost function. Computer simulations are provided for illustration and verification. As control plant the hydrostatic transmission was chosen. The control by using the hydraulic drive is the time variant process, consequential to inconstancy parameters of hydraulic liquid (for instance: kinematic viscosity, compressibility and thickness). The efficiency of pump control is realized by use the electrohydraulic servo - system distinguish itself by a nonlinear characteristic. Finally, a predictive neural network method to control this kind of object is successfully applied.
