  3. 2. Automatic Controller Tuning using Relay-based Model Identification

    Författare :Josefin Berner; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic tuning; Relay feedback; PID control; Model identification; Process control;

    Sammanfattning : Proportional-integral-derivative (PID) controllers are very common in the process industry. In a regular factory there may be hundreds or thousands of them in use. LÄS MER

  4. 3. Control of Multi-Agent Systems with Applications to Distributed Frequency Control Power Systems

    Författare :Martin Andreasson; Karl H. Johansson; Wei Ren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Multi-agent systems are interconnected control systems with many application domains. The first part of this thesis considers nonlinear multi-agent systems, where the control input can be decoupled into a product of a nonlinear gain function depending only on the agent's own state, and a nonlinear interaction function depending on the relative states of the agent's neighbors.

  5. 4. Analysing the transient operation of the boiler and the TES tank for improving the flexibility in biomass CHP

    Författare :Milan Zlatkovikj; Hailong Li; Lei Feng; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; combined heat and power CHP ; boiler; thermal energy storage TES ; feed-forward model predictive control FF MPC ; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The uncertainty in the energy systems due to the continuously growing share of variable renewable energy sources (VRES) increases the requirements for flexibility. From the multiple mechanisms to improve flexibility, biomass-fired combined heat and power plants (CHPs) have gained attention due to their sustainability and high efficiency. LÄS MER

  7. 5. Decentralized Control Design with Limited Plant Model Information

    Författare :Farhad Farokhi; Karl Henrik Johansson; Ather Gattami; Jeff S. Shamma; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Large-scale control systems are often composed of several smaller interconnected units. For these systems, it is common to employ local controllers, which observe and act locally. LÄS MER
