Two degrees of freedom FOPID control loop design via SMDO algorithm

Fopid Design for Load-frequency Control Using Genetic Algorithm

1-Department of Electrical Engineering, Amirkabir University of Technology, Tehran 1591634311, Iran * Corresponding author email: [email protected] ABSTRACT: A fractional order PID (FOPID) for a load frequency control (LFC) is presented in a three-area power system. FOPID controllers are designed the same way as PID controllers are, with the difference that FOPID controllers have five parameters...

Robust Tracking Control of Two-degrees-of-freedom Mobile Robots

A robust tracking controller for a mobile robot with two degrees of freedom has been developed. It is implemented and tested on a real mobile robot. Where other controllers show decreasing performance for low reference velocities, the performance of this controller depends only on the geometry of the reference trajectory. This allows accurate positioning at low speeds, close to obstacles. The d...

Decoupling Multivariable Control with Two Degrees of Freedom

Dynamical Systems with Two Degrees of Freedom.

Shot-noise-limited control-loop noise in an interferometer with multiple degrees of freedom.

Precise measurements, such as those made with interferometric gravitational-wave detectors, require the measurement device to be properly controlled so that the sensitivity can be as high as possible. Mirrors in the interferometer are to be located at specific operation points to isolate laser noise and to accumulate the signal in resonant cavities. On the other hand, rigid control of an auxili...
