  • Conference paper (peer-reviewed)abstract
    • A general description of a flotation process is given. The dynamic model of a MIMO nonlinear subprocess in flotation, i.e. the pulp levels in five compartments in series is developed and the model is verified with real data from a production plant. In order to reject constant disturbances five extra states are introduced and the model is modified. An exact linearization has been made for the non-linear model and a linear quadratic Gaussian controller is proposed based on the linearized model. The simulation result shows an improved performance of the pulp level control when the set points are changed or a disturbance occur. In future the controller will be tested in production
