CONTROL SYSTEMS

A control system is a device or set of devices to manage, command, direct or regulate the behaviour of other devices or systems.CLOSED LOOP CONTROL SYSTEM

There are two common classes of control systems, with many variations and combinations:

i.) logic or sequential controls, and feedback or linear controls.

FEEDBACK CONTROL SYSTEM

ii.) fuzzy logic, which attempts to combine some of the design simplicity of logic with the utility of linear control.

Some devices or systems are inherently not controllable.

The term “control system” may be applied to the essentially manual controls that allow an operator to, for example, close and open a hydraulic press, where the logic requires that it cannot be moved unless safety guards are in place.

SIMULINK

Simulink, developed by The MathWorks, is a tool for modeling, simulating and analyzing multidomain dynamic 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 both drive MATLAB or be scripted from it.

USES OF SIMULINK

Simulink is widely used in control theory and digital signal processing for multidomain simulation and design.

A number of MathWorks and third-party hardware and software products are available for use with Simulink.

SOME THING ABOUT EMBEDDED DESIGN

An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming.Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.

BIONICS

Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of methods and systems found in nature to the study and design of engineering systems and modern technology.Some dictionaries, however, explain the word as being formed from “biology” + “electronics”.

The transfer of technology between lifeforms and synthetic constructs is desirable because evolutionary pressure typically forces natural systems to become highly optimized and efficient. A classical example is the development of dirt- and water-repellent paint (coating) from the observation that the surface of the lotus flower plant is practically unsticky for anything (the lotus effect). Examples of bionics in engineering include the hulls of boats imitating the thick skin of dolphins; sonar, radar, and medical ultrasound imaging imitating the echolocation of bats.

WHAT ARE THE LIMITS OF MATLAB?

LIMITATIONS OF MATLAB

1.)MATLAB is a proprietary product of The MathWorks, so users are subject to vendor lock-in. Some other source languages, however, are partially compatible and provide a migration path.

2.)The language has a mixed heritage with a sometimes erratic syntax. For example, MATLAB uses parentheses, e.g. y = f(x), for both indexing into an array and calling a function. Although this ambiguous syntax can facilitate a switch between a procedure and a lookup table, both of which correspond to mathematical functions, a careful reading of the code may be required to establish the intent.
