This study provides a set of design curves from which effective digital control for an experiment can be obtained and at the same time efficient use of a digital computer shared with other experiments can be realized. The state variable technique is used as both a design method for obtaining the design curves for adaptive sampling and for predicting the states for control of the process. The ad...

aircraft regarding to the elevator deflection angle is designed. The way how the elevator angle affects pitching motion of the aircraft is pointed out, as well as, how a pitch controller can be applied for the aircraft to reach certain pitch angle. In this digital optimal system, the elevator deflection angle and pitching angle of the plane are considered to be input and output respectively. A ...

Abstract – This paper explores predictive digital current programmed control for valley, peak or average current. The control laws are derived for the three basic converters: buck, boost, and buckboost. It is found that for each variable of interest (valley, peak or average current) there is a choice of the appropriate pulse-width modulation method to achieve predictive digital current control ...

The paper presents a software product developed in University comparable with other industrial products. The digital motion control development shell solves the hard real-time constraints imposed by the AC drive control applications. It was developed because of lack of integrated software tools for TMS320C3Cx family. The main advantages of the shell proposed are: high level programming, integra...

this prospective longitudinal study deals with the associations between digital disorders and reproduction indices in dairy cattle on a farm in the vicinity of tehran. it was carried out on 225 postparturient holstein heifers. the evaluation of lameness due to digital disorders on postpartum period of heifers were done and after diagnosis of lameness (based on a 5 points lameness scoring system...

Two digital control applications are presented: velocity control of a DC motor and adaptive system identification and control of an automotive alternator. A tuning method is proposed for DC motors. Experimental application for the DC motor illustrates the effectiveness and the simplicity of the proposed method for controller design. Using adaptive system identification, an automotive alternator...
