This paper describes the implementation of a wireless joystick control for a laboratory-scale trolley crane system. The proposed wireless joystick control system can be used for both educational and research purposes for topics such as human control characteristics identification, human skill evaluation, human control under communication uncertainty etc. Preliminary tests for human controller identification...
This paper presents the PiccSIM Toolchain: a graphical user interface with design tools for the network and control co-simulation platform PiccSIM. The proposed tool-chain enables easy network and control design and improved co-simulation via an integrated graphical user interface. It supports implementation of the simulated algorithms on actual wireless sensor network nodes. The developments presented...
This paper discusses tuning of PED controllers for varying time-delay systems. We analyze the properties of the AMIGO tuning rules of Astrom and Hagglund applied to varying time-delay systems and propose improved tuning rules which increase the robustness to delay variations at the expense of a small degradation in nominal performance. We suggest a tuning scheme that uses the simple AMIGO tuning on...
This paper considers the design of PID controllers for systems with varying time-delays. Using the concept of jitter margin combined with the AMIGO tuning rule methodology, novel tuning rules that are robust to varying time-delays are derived. In addition, we give an expression for the expected lower bound of the jitter margin as these tuning rules are applied. Extensive numerical evaluations demonstrate...
We are introducing a modified scanning light pulse technique (SLPT) setup that can be used to evaluate SiC-based gas-sensitive field-effect devices. This is exemplified with measurements on a Pt-MISiC capacitor that has a metal thickness gradient. The device shows large responses to hydrogen and ammonia in air. The measurement setup is using UV transparent optics together with mechanically chopped...
