A state-of-the-art-technology was used to design the unbalanced three phase motor controller. The fluctuation of line voltage has been questioned in recent times due to the use of heavy powered machine with three phases. This paper is focused on deriving a control scheme to drive a three phase motor that could be used in industry or households. The...

... inverter is used to complement or invert a signal. It has a single input and a single output. The symbol and truth table for the inverter gate are shown in Fig. 3(a) and (b), respectively. In the equivalent transistor circuit of Fig. 4 when a voltage is applied from the output of comparator to A, the transistor will be turned ON, drawing maximum collector current. Hence, whole of Vcc will drop across R thereby sending B to 0V. With 0V applied at A, the transistor will be cut OFF and the output B, ...

Using the method of characteristic analysis and "quasi-equivalent" modeling, we reduce the model of the double loop DC motor control system to a simple non-linear state space model, and then, apply the improved genetic algorithm to accurately identify the model parameters, based on the real rotational speed response. This method is validated by com...
Hardware in the loop testing is increasingly important product testing for cutting down time to market. In my previous article I identified the parameters of a DC motor control system using system identification. An implementation of the resulting transfer function was developed on an ARM based hardware in the loop system and has been verified agai...
Purpose: This study used the uncontrolled manifold (UCM) approach to study joint coordination underlying the control of task-related variables important for success at dart throwing skill. Success at a task can be
achieved, in principle, by always adopting a particular joint combination. In contrast, we adopt a more selective control strategy: var...

To overcome the problem of current control effect being reduced by unideal factors in a motor control system, such as motor parameter variation, inverter dead time, nonlinearity of the system, etc., a sliding mode disturbance observer for an interior permanent magnet synchronous motor is proposed in this paper. The model of an interior permanent ma...

Now-a-day’s technology is running with time, it completely occupied the life style of human beings. Even though there is such an
importance for technology in our routine life there are even people whose life styles are very far to this well known term technology. So it is our
responsibility to design few reliable systems which can be even efficiently used by them. Automatic Room Temperature Controlled Fan Speed
Controller is one of them. The developed system provides an environment in which no user needed to control the fan speed. Automatically control
the fan speed by sensing the room temperature. These fascinating efforts to create intelligent system are to provide human being a more
convenient life. The circuit was designed using electronic components available in local market to keep the cost at low leve
