Abstract AR

خمسة طرق مختلفة للتقليم تم إجراؤها بمحطة بحوث حلفا الجديدة (بشرق السودان) على صنف البرتقال OLinda و ذلك لدراسة أثار تقليم 20 % أفرع، تقليم 40 % أفرع، تقليم جذور، تقليم أفرع 20 % + جذور، تقليم أفرع 40 % + جذور و شاهد (بدون تقليم).

تمخضت نتائج الدراسة على أن طول الأشجار لم يتأثر من جراء تنفيذ هذه المعاملات، و أقل ارتفاع لطول الأشجار رصد عند الشاهد.

زيادة سماكة جذوع الأشجار تأثر معنويا من جراء تنفيذ المعاملات.

نتائج الإنتاجية أسفرت أن وزن الثمار تأثر معنويا في حصاد عامي 1997 و 1998 مع ملاحظة ارتفاع إنتاجية 98 مقارنة مع إنتاجية 1997.

صفات الثمار مقاسه بمتوسط وزن الثمرة نلاحظ الأثر المعنوي في متوسط وزن الثمرة في حصاد عامي 97 و 98.

محتوى عصير الثمار من السكر لم يرصد أي فروقات معنوية في حصاد عامي 97 / 98.

Abstract EN

The control of the electronic throttle in the internal combustion engines for vehicles has gained importance significantly over the past few years.

Throttle control strategies aim to improve the engine performance as per the acceleration, fuel consumption and vehicle drivability.

In this study and towards improving the electronic throttle performance, an integrated feedback control system with proportional-Integral-derivative (PID) controller is designed.

Moreover, hardware-in-loop simulation model is designed and developed.

An experimental work that is based on real time simulation is performed using dSPACE1104 (digital signal processing for control environment) controller board as control test platform.

Matlab is used as modeling environment in order to study the characteristic performance of the control strategy.

The experimental results show an acceptable and good performance of the strategy under different operating conditions in increasing the acceleration, decreasing the fuel consumption and improving the drivability.
