This search includes studying of automated mobile cranes to reduce incidence of inversing which often happens due to payload swaying that requires controlling system at the crane's site to reach Target position and another controlling system to reduce payload swaying as possible while the crane is in motion. Despite the development of controlling systems that adjust the operation and functions of these cranes, the repetition of accidental tips in these cranes lead us to look for hybrid fuzzy controlling system comparing it with PID controlling system. So, it will improve the performance of these cranes through the reduction of payload swaying and precise control of crane’s position. The PID controller and Hybrid Fuzzy PID controller were simulated using Matlab Software and the results were compared to reach the best controlling system for the crane.

Research summary
يتناول هذا البحث دراسة أنظمة التحكم في الرافعات المتحركة المؤتمتة بهدف تقليل حالات انقلابها الناتجة عن تأرجح الحمل. يركز البحث على تصميم نظام تحكم ضبابي هجين ومقارنته بنظام التحكم التناسبي التكاملي التفاضلي (PID) لتحسين أداء الرافعات من خلال تقليل تأرجح الحمل والتحكم الدقيق في موضع الرافعة. تم استخدام برنامج MATLAB لنمذجة ومحاكاة كلا النظامين ومقارنة النتائج للوصول إلى أفضل نظام تحكم. تشمل الدراسة مراحل متعددة بدءًا من النمذجة النظرية للرافعة وتحويلها إلى معادلات رياضية، مرورًا بدراسة نظام التحكم PID، وصولًا إلى تصميم نظام التحكم الضبابي الهجين ومقارنة النتائج النهائية بين النظامين. أظهرت النتائج أن النظام الضبابي الهجين يقدم تحسينات ملحوظة في تقليل تأرجح الحمل، رغم أنه يتطلب زمنًا أطول للوصول إلى الهدف المحدد ويتطلب خبرة أكبر في التصميم.
Critical review
دراسة نقدية: يعد البحث خطوة مهمة نحو تحسين أنظمة التحكم في الرافعات المتحركة، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية المختلفة على أداء النظامين، مثل الرياح أو الاهتزازات الأرضية. ثانيًا، بينما أظهرت النتائج أن النظام الضبابي الهجين يقدم تحسينات في تقليل تأرجح الحمل، إلا أن الزمن الأطول للوصول إلى الهدف قد يكون غير عملي في بعض التطبيقات الصناعية التي تتطلب سرعة عالية. أخيرًا، يتطلب تصميم النظام الضبابي الهجين خبرة كبيرة، مما قد يحد من إمكانية تطبيقه على نطاق واسع دون تدريب مكثف للمهندسين والمشغلين.

In this research a proportional integral differential classic (PID controller) and state feedback controller was designed to control the in the inverted pendulum and a comparison between all the cases and choose the most suitable controller using MATLAB / SIMULINK program
Suspension system is considered one of the most important components of modern automobiles as it is the responsible for the vehicle’s stability, balance and safety. The presence of robust controller is very necessary in order to ensure full interac tion between suspension components and making accurate decisions at the right time. This paper proposes to design an Extended Adaptive Neuro Fuzzy Inference System (EANFIS) controller for suspension system in quarter car model. The proposed controller is used as decision maker In order to contribute in absorbing shocks caused by bumpy roads, and to prevent vibrations from reaching the cockpit. Furthermore, it provides stability and coherence required to reduce the discomfort felt by passengers, which arises from road roughness, which in turn, improve the road handling. The MATLAB Simulink is used to simulate the proposed controller with the controlled model and to display the responses of the controlled model under different types of disturbance. In addition, a comparison between EANFIS controller, Fuzzy controller and open loop model (passive suspension) was done with different types of disturbance on order to evaluate the performance of the proposed model. Controller has shown excelled performance in terms of reducing displacements, velocity and acceleration.
This research presents a mathematic module for stepper motor in Matlab program through the equations that describe the motor transfer function. It illustrates the primary characters of the open loop for the designed module, then it offers PID contr oller design for controlling the motor speed. In addition, we can use the fuzzy logic and its applications in order to design a speed fuzzy controller. Finally, we make a comparison between the fuzzy and PID controller in control performance and response time.
One ofa car's suspension system functions is to isolate vibrations resulting from road on the driver and ensure a comfortable ride. But the design of control systems for semi-active suspension systems is difficult because of the non-linearity of the constituent elements of these systems which make the researches related to it characterized by complexity. So in order to improve the performance of semi-active suspension systems without bearing the effort of designing a model based controller, a control system is designed using self-organizing fuzzy controller based on the principle of delay-in-penalty to control a semi-active suspension system which uses a magneto rheological damper. The controller tries to enhance system performance using the desired response as it is described in the penalty table. The fuzzy logic controller is based on two inputs namely sprung mass velocity and unsprung mass velocity. Using a quarter car model with 2 degree-of-freedom the system is modeled and simulated in MATLAB &Simulink® and the results are compared to the widely used sky-hook strategy. the simulation showed the ability of the self-organizing fuzzy controller to provide good results in minimizing sprung mass acceleration in variousroad profiles compared to sky-hookstrategy.
This paper presents one of the most accurate, stable and fast to response advanced control system (PROPORTIONAL INTEGRAL DIFFERENTIAL CONTROL SYSTEM), which considered one of the special cases of closed loop control systems. Also, display and compare different forms of control and response of sub modes of PID controller, through using programmable logical controller and programmed it to be (PID) controller, and take advantage of this system for accurate control of the three phase motor speed. In addition, the PLC program is been connected to monitoring and collecting data software, known by acronym (SCADA) for calibration of (PID) and use this software to display the result of the responses for the different types of the controller PID in the form of graphic curves. These response curves show accuracy and fast to response that make this application an integrated system that could be form the infrastructure of many practical applications like large cranes, overlapping product lines and different other applications and the use of PLC systems make them high quality and high reliability systems.
