Difference between DC Motor and DC Generator

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts …

Effect of Zeros on System Response

The zeros zj of G(s) do not affect the system stability. However, they do affect the amplitudes of the mode functions in the system response and can block the transmission of certain input signals. In general, to assess the Impact of the zeros on the amplitude of the mode functions, …

Zero State Response using Matlab

Response to a General Input In addition to computing and plotting the impulse and step responses of a system, MATLAB can be used to find and display the response to general functions of time. This is done with the lsim command, which can be used in a variety of ways. …

Impulse Response using Matlab

Impulse Response using Matlab

How to Obtain an Impulse Response Once a transform (or transfer function) G(s) has been defined in MATLAB, operations can be performed to compute and display the corresponding time function g(t), known as the inverse Laplace transform. If the poles are known, G(s) can be written as a partial-fraction expansion …

Transfer Function Calculation Matlab with Example

Transfer Function Example

Transfer Functions Representation Consider a fixed single-input/single-output linear system with input u(t) and output y(t) given by the differential equation $\begin{matrix}   \overset{..}{\mathop{y}}\,+6\overset{.}{\mathop{y}}\,+5y=4\overset{.}{\mathop{u}}\,+3u & \cdots  & (1)  \\\end{matrix}$ Applying the Laplace transform to both sides of (1) with zero initial conditions, we obtain the transfer function of the system from the …

Difference between Core type and Shell type Transformer

Core type Transformer In core type transformers, winding is positioned on two limbs of the core and there is ONLY one flux path and windings are circumventing the core.     These transformers are quite favorite in High voltage practical applications like Distribution, Power, and Auto-Transformers. Shell Type Transformer In …
