Observer-Based Loop Control of Bullblock Drawing Machines

Disturbance Observer Based Closed Loop Force Control for Haptic Feedback

Most commonly used impedance-type haptic interfaces employ open-loop force control under the assumption of pseudostatic interactions. Advanced force control in such interfaces can increase simulation fidelity through improvement of the transparency of the device, and can further improve robustness. However, closed loop force-feedback is limited both due to the bandwidth limitations of force sen...

Observer-Based Control of Piecewise-Affine Systems

This paper presents a new synthesis method for both state and dynamic output feedback control of a class of hybrid systems called piecewise-affine (PWA) systems. The synthesis procedure delivers stabilizing controllers that can be proven to give either asymptotic or exponential convergence rates. The synthesis method builds on existing PWA stability analysis tools by transforming the design int...

Observer-based Control of a Pvtol Aircraft

In this paper, we propose an observed-based control for the PVTOL aircraft considering that the angular position is not measurable. The control strategy presented here, is robust with respect to observer errors and takes into account constraints imposed by the nonlinear observer. The observer design is based on the assumption that the horizontal position is the only available measure. We presen...

Observer-Based Control of Linear Complementarity Systems

In this paper, we will present observer and output-based controller design methods for linear complementarity systems (LCS) employing a passivity approach. Given various inherent properties of LCS, such as the presence of state jumps, mode dynamics described by DAEs, and regions (“invariants”) for certain modes being lower dimensional, several proposed observers and controllers for other classe...
