    Exact linearization is often applied to nonlinear processes. This method requires not only the knowledge of the model structure but also the accurate parameter values. If the real parameter values of the controlled process are different from the nominal values used for the exact linearization, the resulting system may not be linear or may have different gains and time constants as expected. A simp... View full abstract»

    Homogeneous cooling of a metallic plate with the help of thermoelectric elements is crucial in terms of using it as a clamping device. By applying water on a plate and chilling it under sub-zero temperatures the resulting ice structure is able to fix workpieces form-fitted, ensuring proper holding and clamping forces for upcoming machining operations. For this purpose a number of thermoelectric co... View full abstract»

  • Robust nonlinear model predictive control with reduction of uncertainty via dual control

    Publication Year: 2017, Page(s):48 - 53
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (355 KB) | HTML iconHTML

    Dual control is a technique that solves the tradeoff between using the input signal for the excitation of the system excitation signal (probing actions) and controlling it, which results in a better estimation of the unknown parameters and therefore in a better (tracking or economic) performance. In this paper we present a dual control approach for multistage robust NMPC where the uncertainty is r... View full abstract»

    The most widely used controllers in industry are still the proportional, integral, and derivative (PID) and discrete-time proportional, summation, and difference (PSD) controllers, thanks to their simplicity and performance characteristics. However, with these conventional fixed gain controllers we could have difficulties to handle nonlinear or time-variant characteristics. The introduction of lin... View full abstract»

    In the last few years, variable engine valve control has attracted a lot of attention because of its ability to reduce pumping losses and increase torque performance over a wider speed and load range. Variable valve timing also allows control of internal exhaust gas recirculation, thus improving fuel economy and reducing NOx emissions. One of the most important issues in this context is...
