Control Systems Overview


A control system is a device or set of devices that manage and regulate the behavior of other devices to achieve desired results.

Linear Systems


Linear control systems adhere to principles of homogeneity and additivity, ensuring consistent and proportional responses.


 

Non-Linear Systems


Non-linear control systems do not follow linear rules, often resulting in behavior that varies significantly with different inputs.

Digital vs Analog


Digital systems provide improved accuracy, reliability, and efficiency over analog systems, especially in handling non-linear control systems.


 

 

Single Input Single Output Systems


These are also known as SISO type of system. In this, the system has single input for a single output. Various example of this kind of system may include temperature control, position control system, etc.


 

Multiple Input Multiple Output Systems


Known as MIMO systems, these have multiple outputs for multiple inputs. Examples include Programmable Logic Controllers (PLC) among others.


 

Lumped Parameter System


In these types of control systems, the various active and passive components are assumed to be concentrated at a point and that’s why these are called lumped parameter type of system. Analysis of such type of system is very easy which includes differential equations.


 

Distributed Parameter System


In these types of control systems, the various active (like inductors and capacitors) and passive parameters (resistor) are assumed to be distributed uniformly along the length and that’s why these are called distributed parameter type of system. Analysis of such type of system is slightly difficult which includes partial differential equations.

What is Voltage Stability in Power Systems?
What is Voltage Stability in Power Systems?
Definition of Voltage StabilityVoltage stability in a power system is defined as the ability to maintain acceptable voltages at all buses under both normal operating conditions and after being subjected to a disturbance. In normal operation, the system’s voltages remain stable; however, when a fault or disturbance occurs, voltage instability may arise, leading to a progressive and uncontrollable voltage decline. Voltage stability is sometimes referred to as "load stability."Voltage instability c

What is Dual Trace Oscilloscope?DefinitionA dual-trace oscilloscope uses a single electron beam to generate two separate traces, each deflected by an independent input source. To produce these two traces, it primarily employs two operating modes—alternate mode and chopped mode—controlled by a switch.Purpose of a Dual-Trace OscilloscopeWhen analyzing or studying multiple electronic circuits, comparing their voltage characteristics is often critical. While one could use multiple oscilloscopes for

What is Cathode Ray Oscilloscope (CRO)?
What is Cathode Ray Oscilloscope (CRO)?DefinitionA cathode ray oscilloscope (CRO) is an electrical instrument for measuring, analyzing and visualizing waveforms and other electronic/electrical phenomena. As a high - speed X - Y plotter, it shows an input signal against another signal or time. Capable of analyzing waveforms, transient phenomena and time - varying quantities across a wide frequency range (from very low to radio frequencies), it mainly operates on voltage. Other physical quantities

What is Automatic Voltage Regulator?
What is Automatic Voltage Regulator?
An automatic voltage regulator is employed to regulate voltage, converting fluctuating voltages into a constant one. Voltage fluctuations mainly stem from variations in the load on the supply system. Such voltage variations can damage the equipment within the power system. These fluctuations can be mitigated by installing voltage - control equipment at various locations, such as near transformers, generators, and feeders. Multiple voltage regulators are often placed throughout the power system t
