This work is devoted to the important problem of the contemporary automatic control theory – creation of integrated technologies of design of ACS (Automatic Control Systems). Such technologies must provide complex solution of the controlled object’s state evaluation and synthesis of the control law. The main practical result would be ACS accuracy increase. The new concept of ACS design for realization of integrated technologies conditions the urgency to confirm its efficacy’s by applied results in creation of concrete working systems. Research in this direction of automatic control theory is at its initial stage, at which it is important to evaluate possibilities of new technologies on simple ACS’ functioning models. The author presents a model of a one-channel attitude control system for a platform based on an angular velocity sensor providing instantaneous posterior estimation of platform’s rotation angle error. Values of the disturbance torque, acting on the platform, and angular velocity measurement errors on the considered observation interval are set as random numbers that stay constant on this interval. The author presents the analysis of control and state evaluation for the object of control, implemented by the synthesized system for two versions of the object: in the absence and in the presence of its own damping torque. The author demonstrates a modification of adjuster’s structure to achieve accuracy increase for the platform’s parameters evaluation.

A new design technique about pulse magnetron sputtering control system Which bases on multifunction controller and automatic control theory is proposed. This system includes a host PC, a gust multifunctional controller and the local instruments. It controls the process of films deposition automatically and it is also composed of three models corresponding for different operational requests. The characteristic of sputtering deposition films shows the steadily and effectively advantages in this technique.

Recently, with the rapid agricultural application progress in China, greenhouse control issues have been better addressed. The greenhouse control technology, as an emerging technology, is increasingly being widespread attended, and is gradually walking in the direction of constructing good quality, high output efficiency agricultural systems. In this new situation, we need to carry out market research, carefully research the greenhouse automatic control theory based on SCM technology, and design automation control system with best effect. The performance test result shows: This new system has a good usable performance, while related technology can provide a scientific basis for further research in the future. Keywords.Microcontroller; greenhouse automatic control.
