In this paper, bath control is proposed for the electroless nickel plating through holes board process. The main parameters of the product (board) – thickness of the plat-ing film and phosphorous content – are stabilized at constant levels using optimal tracking control. The set point for control is calculated from the model in dependence on the current… (More)
The identification problem of nonlinear model for electroless nickel plating is considered in this paper. The identification method is developed for estimation of the constant electrochemical parameters and time-varying mixed potential parameters. The efficiency of the method proposed is demonstrated in the simulation experiment.
The mass and heat balance in a multi-stage flash evaporator in once-through configuration is modelled with partial differential equations (PDEs) derived from a system of ordinary differential equations (ODEs) that represents a cascade of vacuum tanks. The derived PDE model represents the pressure head, temperature and salinity evolution in the cascade… (More)
