A combination or arrangement of a number of different physical components to form a whole unit such that that combining unit performs to achieve a certain goal.

The action to command, direct or regulate a system.

The part or component of a system that is required to be controlled.

It is the signal or excitation supplied to a control system.

It is the actual response obtained from the control system.

The part or component of a system that controls the plant.

The signal that has adverse effect on the performance of a control system.

A system that can command, direct or regulate itself or another system to achieve a certain goal.

The control of a process by automatic means

An interconnection of components forming a system configuration that will provide a desired response.

It is the device that causes the process to provide the output. It is the device that provides the motive power to the process.

The process of conceiving or inventing the forms, parts, and details of system to achieve a specified purpose.

A model of a system that is used to investigate the behaviour of a system by utilizing actual input signals.

The adjustment of the parameters to achieve the most favourable or Advantageous design.

A measure of the output of the system used for feedback to control the system.

The output signal is feedback so that it subtracts from the input signal.

Unidirectional, operational blocks that represent the transfer functions of the elements of the system.

A diagram that consists of nodes connected by several directed branches and that is a graphical representation of a set of linear relations.

Statements that explicitly state what the device or product is to be and to do. It is also defined as a set of prescribed performance criteria.

A system that utilizes a device to control the process without using feedback. Thus the output has no effect upon the signal to the process.

A system that uses a measurement of the output and compares it with the desired output.

The control system where the desired values of the controlled outputs are more or less fixed and the main problem is to reject disturbance effects.

The control system where the outputs are mechanical quantities like acceleration, velocity or position.

It is a notion that describes whether the system will be able to follow the input command. In a non-rigorous sense, a system is said to be unstable if its output is out of control or increases without bound.

A system with more than one input variable or more than one output variable.

The result of making a judgment about how much compromise must be made between conflicting criteria.

It is a control system that is created by nature, i.e. solar system, digestive system of any animal, etc.

and transfer functions are used to analyze and design control systems.

algebra simplifies complex systems by combining blocks into simpler ones.

Represent the elements of a control system using blocks. Each block has a transfer function that models the input-output behavior of that element.

Represent the relationship between the input and output of each block.

Used to simplify complex systems by combining blocks into simpler ones.

Combine multiple input signals into one.

Represent the direction of the flow of information or signal.

Block diagram algebra is a graphical representation used in control and signal processing.

Understanding the basic components and operations of block diagrams is crucial for simplifying the process of

Represent system processes or functions. Each block has an input and an output, typically indicating how the system transforms the input.

These are denoted by a circle with multiple arrows pointing in and one arrow out. It shows where signals are algebraically summed before being sent to the next block.

Split a single signal path into multiple ones, allowing the same signal to enter several different blocks simultaneously.

is an essential tool used in control system engineering to simplify the analysis of complex systems.

multiple inputs are algebraically added or subtracted at a single point. It is visually represented by a circular node with arrows representing incoming and outgoing signals.

This involves splitting a signal so that it can enter multiple pathways simultaneously. This is useful for distributing the same input to various system components.

Understanding block diagram algebra is essential for deriving the ___ ___ of a system, which describes its input-output relationship in the Laplace domain.

It is a graphical representation used in control systems to depict relationships and flow between system components.

Include blocks (representing functions), lines (indicating signal flow), summation points, and branch points.

Involves adding transfer functions when blocks share the same input and their outputs are summed.

The transfer tunction is given by for negative feedback in a control system.

Block diagram algebra techniques are used in applications like automobile speed control and robotic arm precision.
