Modeling and Simulation of Control Actuation System
In this paper a dynamic simulation model is implemented using Fuzzy logic controlled Brushless direct current motor drives for fin control actuation. The Brushless direct current (BLDC) motor is modeled using MATLABSIMULINK models and controlled by fuzzy logic controller. In addition to this, current hysterias controller block, inverter block and speed estimated block, entire blocks are modeled...
متن کاملHigh Frequency Modeling of a Hydraulic Actuation Flight Control System
The objective of this work was to develop a high fidelity model representative on high frequencies of a FCS with an active-active hydraulic actuation. The performance for step input and frequency response were analyzed, showing to be a model close to a real system and representative even in high frequencies.
متن کاملModeling supply and return line dynamics for an electrohydraulic actuation system.
This paper presents a model of an electrohydraulic fatigue testing system that emphasizes components upstream of the servovalve and actuator. Experiments showed that there are significant supply and return pressure fluctuations at the respective ports of the servovalve. The model presented allows prediction of these fluctuations in the time domain in a modular manner. An assessment of design ch...

متن کاملReal World Modeling and Nonlinear Control of an Electrohydraulic Driven Clutch
In this paper, a complete model of an electro hydraulic driven dry clutch along with its performance evaluation has elucidated. Through precision modeling, a complete nonlinear physical and full order sketch of clutch has drawn. Ultimate nonlinearities existent in the system prohibits it from being controlled by conventional linear control algorithms and to compensate the behavior of the sy...
