A New Approach for Robust Optimization Based Open- and Closed-Loop Control of Nonlinear Processes

Keywords: robust closed-loop process control, robust trajectory, unscented transformation, NMPC

This paper presents a new approach for robust open-loop and closed-loop control of nonlinear processes with parameter uncertainties and a comparision with classical approaches. The algorithm uses the Unscented Transformation. It allows the calculation of statistic moments of the system´s output as a function of stochastic system states and model parameters. Because the numerical burden is low, it can be used for optimization based online closed-loop process control as well.
