An ionic polymer metal composite (IPMC) actuator is an Electro-Active Polymer (EAP) that bends in response to a small applied electrical field as a result of mobility of cations in the polymer network. This paper proposes a dynamic fuzzy Nonlinear Auto Regressive Exogenous (NARX) model for modeling and identifying the nonlinear behavior of on type IPMC(More)
Nowadays, hydraulic actuators play an important role in a modern industry where controlled force or position with high accuracy is the most significant demand. This paper presents a new kind of electric-hydraulic load simulator (HLS) for conducting performance and stability test in the bench system where force control is important. The system model consists(More)
Nowadays, magneto-rheological (MR) fluid dampers (MRD) are widely used for the semi-active suspension control in vibration community. However, the inherent nonlinear nature of the MRD causes challenges for damping control of the suspension system using this device with high performance. Therefore, the development of an accurate modeling method for a MRD is(More)
This paper proposed the face detection and tracking system using a embedded computing system for humanoid robot environment which allows the user to observe of recognize an unknown person. For detection faces in image sequence, the system uses the skin color model and deformable ellipse matching. Faces in a view are detected by maximizing the image gradient(More)
This paper presents a simple and precise wave prediction method for applications to real-time control of wave energy converters (WECs). The proposed prediction method is based on a so-called modified grey model with first order - one variable - MGM(1,1). This model was developed from the conventional grey model - GM(1,1) in which the background series used(More)
This paper presents an accurate position control for a pump-controlled electro-hydraulic actuator (EHA) using time-delay estimation (TDE). The TDE technique is used to estimate nonlinear terms of EHA, which is a third order nonlinear system. The measured signal of linear encoder, and pressure of the EHA are used to implement the TDE technique. The(More)
An ion polymer metal composite (IPMC) is an Electro-Active Polymer (EAP) that bends in response to a small electrical field as a result of mobility of cations in the polymer network and vice versa. A typical IPMC sheet is constructed with a thin ionic polymer membrane and two metal electrode layers outside. This paper proposes an idea to estimate the(More)
