Temperature is an important environmental parameter in greenhouse, how to control the temperature accurately with a unified method is an important task in greenhouse automatic control system. This paper introduces the design of the fuzzy control node of temperature in greenhouse based on a MCS196 Micro-computer and the component of the greenhouse control system. The fuzzy control principle and ...

A neural network that was designed to control a Spirulina aquaculture process in a pilot plant in the north of Chile, is presented in this work. Spirulina is a super food, but is a delicate alga and its culture may be suddenly lost by rapid changes in the weather that can affect its temperature, salinity or pH. The neural network control system presented is complex and non linear, and has sever...

The problem of optimal control for nonlinear systems is considered. Genetic programming is used to obtain functional dependence of control vector from problem space vector. Network operator is proposed as one of possible solutions for effective calculations. The problem of structure-parametric synthesis of satellite angular movement stabilization system is described.

In order to adapt to the requirements of the development for precision agriculture technology, making the rice seed tape planting technology has been widely used. The paper-making improved the design on the rice seed tape twisting machine especially the seed tape winding units. It proposed seed tape winding automatic control system based on STC90C514AD to realize the rotating speed adjustment o...

In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...

In this paper, in order to control uncertain chaotic system, an adaptive fuzzy control(AFC) scheme is developed for the multi-input/multi-output plants represented by the Takagi-Sugeno(T-S) fuzzy models. The proposed AFC scheme provides robust tracking of a desired signal for the T-S fuzzy systems with uncertain parameters. The developed control law and adaptive law guarantee the boundedness of...

Agricultural subsidies in the context of the Common Agricultural Policy (CAP) represent over 40% of the EU’s yearly budget. To ensure that funds are properly spent, farmers are controlled by National Control and Paying Agencies (NCPA) using tools, such as computer-assisted photo interpretation (CAPI), which aims at identifying crops via remotely-sensed imagery. CAPI is time consuming and requir...
