Arm cortex ( lpc 2148 ) based motor speed control Uday Wankar
The project is designed to control the speed of a DC and AC motor using an ARM7 LPC2148 processor. The speed of motor is directly proportional to the voltage applied across its terminals. Hence, if voltage across motor terminal is varied, then speed can also be varied. This project uses the above principle to control the speed of the motor by varying the duty cycle of the pulses applied to it, popularly known as PWM control. The project uses input button interfaced to the processor, which are used to control the speed of motor. Pulse Width Modulation is generated at the output by the microcontroller as per the program. The program is written in Embedded C.
The average voltage given or the average current flowing through the motor will change depending on the duty cycle, ON and OFF time of the pulses, so the speed of the motor will change. A motor driver IC is interfaced to the ARM7 LPC2148 processor board for receiving PWM signals and delivering desired output for speed control. Further the project can be enhanced by using power electronic devices such as IGBTs to achieve speed control higher capacity industrial motors.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

The main core of this project is to design a control
system for DC motor by using Microcontroller.
This control system works on the principle of PID
Controller and Pulse Width Modulation which will be able
to control the DC motor speed at desired speed regardless
the change of load.
This system will be also able to perform operations
like start and stop on motor at desired position of load.

Same circuit can be used for stepper motor control..
GSM Module can be used to make the control possible with
mobile messages..
This system can be used in industrial controlling drives because of
its improved accuracy and fast dynamic response just by modifying
following issues:-
Feedback Measurement (Encoder)
Control Algorithm (Microcontroller)
Switching Module (Motor Driver Circuit)

The direction (forward/reverse) of the motor is also controlled.
Control and operation of drive is flexible due to the user friendly
menu, keyboard and LCD display.
The speed of the motor is controlled accurately using
microcontroller ATmega32 having PID algorithm.
In the condition of the load variation the speed of the motor is
maintained constant with the designed algorithm.
Position is controlled accurately using PID algorithm and
feedback pulses from the encoder in order to develop a precise
system.
