A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance.
Reluctance motor sub types include synchronous, variable, switched and variable stepping.
Reluctance motors can deliver high power density at low cost, making them attractive for many applications. Disadvantages include high torque ripple (the difference between maximum and minimum torque during one revolution) when operated at low speed, and noise due to torque ripple.

Speed Control of DC Motor under Varying Load Using PID ControllerCSCJournals
DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller. A Matlab simulation of proposed system with no-Load and full-load condition is performed on Simulink platform to observe the system response. The motor speed is kept constant in this experiment. The simulation result of the experiment shows that a motor is running approximately at a constant speed regardless of a motor load. The Simulink results show that the speed of the motor is slow down only for about 270 rpm (9%) in 980 milliseconds under the effect of full load. However, the motor speed is hunting about 200 rpm (6.66%) in 900 milliseconds on unloading condition. It is concluded that a PID controller is successful tool for controlling the motor speed in presence of load disturbances.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. • Adjustable speed drive (ASD) describes
equipment used to control the speed of
machinery. Many industrial processes such as
assembly lines must operate at different
speeds for different products. Where process
conditions demand adjustment of flow from a
pump or fan, varying the speed of the drive
may save energy compared with other
techniques for flow control.
3. • Where speeds may be selected from several
different pre-set ranges, usually the drive is
said to be adjustable speed. If the output
speed can be changed without steps over a
range, the drive is usually referred to as
variable speed.
4.
5. • There are mainly two way to control the speed
of D.C. motors
(1) Direct-current motors allow for changes of
speed by adjusting the shunt field current.
(2) Another way of changing speed of a direct
current motor is to change the voltage
applied to the armature.
6. • In our project we used to control the armature
Voltage to control the speed of the motor at the
Various given loading conditions .
7. • The controlling of motor armature voltage is
done with the help of PWM .
• The direction of motor is controlled by H-
bridge.
• There are rotational sensors are placed to
measure the speed(RPM) and angular
displacement of the motor.
• The Simulink modal is shown next.
8.
9. • An H bridge is an electronic circuit that
enables a voltage to be applied across a load
in either direction. These circuits are often
used in robotics and other applications to
allow DC motors to run forwards and
backwards.
10. • The H-bridge arrangement is
generally used to reverse the
polarity of the motor, but can
also be used to 'brake' the
motor, where the motor comes
to a sudden stop, as the
motor's terminals are shorted,
or to let the motor 'free run' to
a stop, as the motor is
effectively disconnected from
the circuit. The following table
summarizes operation, with
S1-S4 corresponding to the
diagram above.
11. • In the previous presentation we shown a
Simulink modal of D.C. drive.
• Which has the variation in the speed with
respect to the load as per the Simulink results.
• For improvement in this section we maintain
the constant speed of the motor (D.C.) at the
various loading conditions.
12. • In the above shown model there are problem with the
feedback network which we are used .
• We compare the output speed(RPM) and the set
speed(which) required to generate the error signal.
• But this error signal does not provided proper
feedback to the supply .
14. • The feedback is applied through Hall sensor .
• The output of the Hall effect sensor is compare with
the rated speed and speed controller gives the
equivalent voltage to the current controller which
produce the equivalent voltage as per the requirement
of the load.
• The improved Simulink model is given below.
20. • As we seen that the applied load torque is
different at the various time intervals.
• The speed should be kept constant in these
time intervals.
• The variation of the speed and armature
voltage given by the simulation result shown
next.
21.
22.
23. • As shown in the above graph the speed on the
motor kept constant to the set value of the
speed(2500 RPM).
• Which is equal to the rated speed of the
motor.
24. • We connect the drive circuit in fan load and
the automobile load .
• On connecting the load on these load we the
behavior of the drive circuit.
• The both of the models and there output
results are given as below.

31.
32.
33. • The drive works on the fan load as per the
requirement .
• But on the automobile load the drive try to
limit the rpm as per the demand but after
some time it does not control the motion.
34. • We given the speed as per the requirement of
the load and this set speed compare the
speed with the output and generate the error
signal to control the motion of the motor as
per the need.
• But it can also be automatically controlled for
example by using a rotational detector such as
a Gray code optical encoder.
