Recent advances in robotics have led to the development of exoskeleton robots that are becoming extensively used in the medical domain, to assist and help people suffering from physical impairments recover mobility. Most of existing controllers designed for position control of exoskeleton robots are linear which may not be suitable for exoskeleton robots having complex structures under heavy uncertainties...
Pneumatic artificial muscles are very powerful pneumatic actuators that work very similarly to the human muscle. They are broadly used in the development of robotic manipulators for industry or in the medical domain mainly for their low cost, intrinsic safety and high compliance. However, devices driven by these actuators are characterized by complex nonlinear dynamics and time varying properties...
Filtering strategies play an important role in estimation theory, and are used to extract knowledge of the true states typically from noisy measurements or observations made of the system. This paper describes a novel approach that combines the information given by an odometer and a laser range finder sensors to efficiently solve the Simultaneous Localization and Mapping (SLAM) problem of the Unmanned...
This paper proposes a hybrid control scheme based on Non-singular Terminal Sliding Mode Control (NTSMC), Higher Order Sliding Mode (HOMS) and Neural Network (NN) structure for n-DOF robot manipulator. The NTSMC is used with time delay estimation method (TDE). Through TDE the equivalent control is designed without needs of system model. The HOMS consists of the Super Twisting algorithm which is estimated...
Pneumatic artificial muscles are widely used in the field of robotics in the development of robot manipulators to help or assist human beings. This can be attributed to their inherent compliance and low cost. However, their highly nonlinear dynamics and their time varying properties, make it challenging for classical controllers to accurately control such systems. Sliding mode control is a powerful...
In this work is treated the design of two controllers applied to a fixed-wing unmanned aerial vehicle (UAV). The aim is to stabilize an UAV type Cessna 182 in longitudinal and in lateral-directional flight. The UAV is identified by decoupling the system to longitudinal and lateral-directional modes and using off line modeling. The resulting models represent approximately the UAV because of nonlinearities...
