Conducting polymers actuators (CPAs) are potential candidates for replacing conventional actuators in various fields, such as robotics and biomedical engineering, due to their advantageous properties, which includes their low cost, light weight, low actuation voltage and biocompatibility. As these actuators are very suitable for use in micro-nano manipulation and in injection devices in which t...

In this paper, the designed schemes for two fuzzy controllers, Mamdani fuzzy controller and Takagi-Sugeno fuzzy controller, through the scaling factor adaptation are proposed. The proposed adaptation laws for the output scaling factor, which respectively result from the direct adaptive approach, are used to appropriately determine the control signal of the fuzzy controllers. The great advantage...

The main drawback of "classical" fuzzy systems is the inability to design and maintain their database. To overcome this disadvantage many types of extensions adding the adaptivity property to those systems were designed. This paper deals with one of them a new hybrid adaptation structure, called gradient-incremental adaptive fuzzy controller connecting gradient-descent methods with the so-calle...

Deriving the analytical structure of fuzzy controllers is very important as it creates a solid foundation for better understanding, insightful analysis, and more e1ective design of fuzzy control systems. We previously developed a technique for deriving the analytical structure of the fuzzy controllers that use Zadeh fuzzy AND operator and the symmetric, identical trapezoidal or triangular input...

In this work we consider the application of an adaptive neural network control for a class of single input single output non linear systems. The method uses a neural network system of Radial Basis Function (RBF) type to approximate the feedback linearization law and a fuzzy inference system of Mamdani type to estimate the control signal error between the ideal unknown control signal and the act...

This work presents a horizontal velocity controller for the unmanned helicopter APID MKI11 by Scandicraft AB in Sweden. We use a novel approach to the design consisting of two steps: first, a Mamdani-type of fuzzy rules compute for each desired horizontal velocity the corresponding desired values for the attitude angles and the main rotor collective pitch; second, a TakagiSugeno controller is u...
