Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted ...
VisSim/Altair Embed is used in control system design and digital signal processing for multi-domain simulation and design. [1] It includes blocks for arithmetic, boolean, and transcendental functions, as well as digital filters, transfer functions, numerical integration and interactive plotting. [2]
The basis of a STATCOM is a voltage source converter (VSC) connected in series with some type of reactance, either a fixed Inductor or a Power Transformer.This allows a STATCOM to control power flow much like a Transmission Line, albeit without any active (real) power flow. [12]
Ideally, an embedded system would be tested against the real plant, but most of the time the real plant itself imposes limitations in terms of the scope of the testing. For example, testing an engine control unit as a real plant can create the following dangerous conditions for the test engineer:
Stateflow (developed by MathWorks) is a control logic tool used to model reactive systems via state machines and flow charts within a Simulink model. Stateflow uses a variant of the finite-state machine notation established by David Harel, enabling the representation of hierarchy, parallelism and history within a state chart.
The PLECS software is available in two editions: PLECS Blockset for integration with MATLAB®/Simulink®, and PLECS Standalone, a completely independent product. When using PLECS Blockset, the control loops are usually created in Simulink, while the electrical circuits are modelled in PLECS. PLECS Standalone on the other hand can be operated ...
A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.
The recording of a heart beat (an ECG), may be corrupted by noise from the AC mains.The exact frequency of the power and its harmonics may vary from moment to moment.. One way to remove the noise is to filter the signal with a notch filter at the mains frequency and its vicinity, but this could excessively degrade the quality of the ECG since the heart beat would also likely have frequency ...
