This paper describes an experimental comparison of two alternative nonlinear automotive speed control systems. The rst approach is based on interpolation of multiple linear controllers designed using multiple local linear models. The second approach is based upon geometric nonlinear control theory and utilises feedback linearisation. This paper focuses on engineering aspects and experimental co...

Current Source Inverter(CSI) has applications in the area of current protection. For CSI fed loads, when connected at a point of common coupling (PCC), the system voltage, may not always be a pure sinusoidal waveform, due to distortions created by other loads at the PCC. This paper presents two simple controllers, namely the comparator type and PI type, to derive and generate a constant current...

The paper deals with the design of decentralized robust controllers with output feedback for a class of interconnected linear continuous time systems with parametric uncertainties. The uncertainties, in general nonlinear, can appear both in the subsystems as well as in their interconnections. No matching conditions or other similar constraints are to be considered in the complex uncertain syste...

This technical note outlines an approach to the problem of synthesizing fixedstructure low-order controllers for systems whose mathematical models are unknown, but their frequency responses are available. Stability of the closed-loop system is guaranteed if the frequency response of the plant and the controller satisfy certain conditions at specific frequencies. It is shown that the relation be...

In the last decade, non-integer order controllers have received great attention, due to their capacity of achieving robustness of the controlled loops with respect to gain and parameter variations of the plant. However, despite the general interest, technical literature offers few widely accepted and easy tuning techniques for these new controllers. To overcome the lack of simple tuning rules, ...

Path integral (PI) control defines a general class of control problems for which the optimal control computation is equivalent to an inference problem that can be solved by evaluation of a path integral over state trajectories. However, this potential is mostly unused in real-world problems because of two main limitations: first, current approaches can typically only be applied to learn openloo...

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...
