Abstract: The purpose in this paper is the design of the control to switching power supply for small perturbations. By the theoretical analysis and calculation, with the output filter inductor current and filter capacitor voltage switching power supply as two state variables, the conclusion is that control of the output filter inductor current sampling do well in the anti-jamming. The simulation is made for verification. And comparing the results, the current control mode shows a very strong anti-interference ability.

Abstract: In order to study fenoxycarb emulsion, bitter smoke EC, Shuai Qi, avermectin Chinolyda flagellicornis of four pesticides on the larvae of the control effects, from the Three Gorges Badong County in Hubei Province were collected in flat farm hazards with sawfly eggs The cedar branches, larvae hatched in the laboratory. Pesticide use for each of 9 repeat, repeat every 5 hours, 24 hours, 48 hours of observation time the number of larvae died. Since each branch the number of different insects, in percentage terms. Of variance, multiple comparisons were the best abamectin, fenoxycarb emulsion is not obvious, there is interaction.

Abstract: The soil’s temperature plays an important role of soil ecology research. In order to gain and control soil’ temperature. A control system is proposed for soil’s temperature. And a new control algorithm which is based on the PID algorithm is designed in the control system to handle the complex change of the soil’s temperature. It does not need to know the mathematical model of soil’s temperature. At last, the control result is analyzed in this paper. The result shows that the soil’s temperature is controlled ideal by this control system which is accurate to 0.5°C.

Abstract: Energy savings are an important issue in the context of climate change. The main goal of researchers is to study and develop new methods of improving energy efficiency in household heating. In this paper a Matlab toolbox is presented and explained. The toolbox is developed for researchers and students interested in simulating building energy behavior. A test room is developed and simulated and a radiator model is implemented. Two types of heating are used during the simulation: a radiant floor heating and a panel radiator. A simple on-off control is used for each heating system. The goal of the paper is to study the impact on energy consumption of each heating system used and their impact on energy consumption when the two heating systems are used in different configurations.

Abstract: In order to ensure the quality of marine gas turbine generation set, its speed must maintain constant. Due to rising or falling power demand, the real and reactive power balance is harmed and hence the turbine output speed gets deviated from nominal value. This necessitates the need for an intelligent fuzzy controller to generate and deliver power in an interconnected system as economically and reliably as possible while maintaining the power turbine speed within permissible limits. The design of complex parameter self-tuning fuzzy control system and efficient simulation were achieved. The models were simulated for different load conditions in order to demonstrate the effectiveness of the proposed controller. Simulation results emphasized the improved performance in comparison with fixed gain controllers. The proposed method overcomes the drawbacks of a conventional fixed gain controller and improvement was achieved in terms of settling time, oscillations and overshoot.

Abstract: Since the past years, the microprocessor (8051) has been still playing an indispensable role as a controller in industry applications because of fast executing process, low-cost, small size and low power consumption, etc. It, however, usually lacks of long distance transmission, graphical interface and vision. On the other hand, VB is now a very popular software package for graphical interface design due to easy exploring and low price. Combining both superiorities as above, this paper develops a remote visional microprocessor-based monitoring and control platform using VB graphical interface. The nearby PC (server) can collect real-time sensing signals from the 8051 through RS232 and transmit it to remote PCs (client) for on line monitoring mechanism via Internet. Also, the client can send the control signals to the server and thus control the 8051. The real-time case study for feeding care in the Pet House is provided to verify its well performance and remote Web-based capability in term of fast, simple and robust performance.

Abstract: This paper proposes a new approach to achieving the command and control modules that can be embedded in smart home building. As a result of this new approach, the house, which in the classical sense, corresponds to everyday family activities, becomes a place that can be monitored and controlled in real time, to ensure comfort their occupants. The embedded equipment can be sensors for data collection, actuators for operating various functions and a control unit which records data on which decisions can be made complex. The software programming used is Lab View. The challenge is determining how "smart home" is able to communicate with all components.

Abstract: The steering radius and the vehicle velocity is utilized to control the drive force and steering angle of each electric-wheel in this essay. In order to improve the characteristics of vehicle, a dynamic simulation was made with the predictions of constant velocity and radius to the vehicle model with the R-v control strategy. This simulation proves that the characteristics of vehicle steering will be better with the utilization of this control strategy.
