Accuracy Comparison of Arx and Anfis Model of an Electro-hydraulic Actuator System
Precise control of electro-hydraulic actuator (EHA) system has been an interesting subject due to its nonlinearities and uncertainties characteristics. Good control can be designed when precise model of the system is available. Linear ARX modelling has widely been applied and satisfying result has been obtained, through linearization process. The objective of this paper is to compare ARX model ...
متن کاملSelf-tuning Control of an Electro-hydraulic Actuator System
Due to time-varying effects in electro-hydraulic actuator (EHA) system parameters, a selftuning control algorithm using pole placement and recursive identification is presented. A discrete-time model is developed using system identification method to represent the EHA system and residual analysis is used for model validation. A recursive least square (RLS) method with covariance resetting techn...
متن کاملSystem Identification and Model Validation of Electro- Hydraulic Actuator for Quarter Car System
Electro-Hydraulic actuator is common tools used in the industries. This is due to accurate positioning toward the load and fast response make it as major instruments for the industries process. This paper presents experimental work on non-recursive identification of electro-hydraulic actuator system that represented by a discrete-time model in open-loop configuration. A least square method is u...
متن کاملIdentification of Electro-hydraulic Actuator Using Fractional Model
Electro-hydraulic actuator (EHA system) identification is to describe the characteristic of the system that useful for prediction or control system design. There are numerous methods of EHA modeling but there has not been much model using fractional-order (FO) model. In this work, integer-order (IO) model and FO model are developed to model EHA system. Output-error method is used as the estimat...
متن کاملMathematical Modeling of an electro-hydraulic actuator for humanoid robots
The work presented in this paper is based on a novel integrated and compact hydraulic robotic actuator [1] (BIA patentUS20110085922), intended for the hydraulic humanoid robot HYDROïD. This actuator solves the problem of autonomy for hydraulic humanoid robots as it can be integrated to operate each joint separately. Thus, eliminating the need for a central hydraulic power pack. Also, due to its...
