−In the paper you will implement a set point control system for the single-link manipulator with flexible joint using a multiloop controller based on feedback linearization (inner loop) and linear statefeedback control (outer loop). Then, you will modify the multiloop controller to solve a trajectory tracking problem. The simulations demonstrate that the multi-loop control law it is a viable me...

This article presents an application of the multivariable Model-based Predictive Controller associated to a Kalman filter to damp the mechanical vibrations of a flexible one-link manipulator using state variables feedback. The flexible manipulator, seen as a single input multiple outputs system is modelled using the Lagrange equations. The state space equations are expressed in order to simplif...

A new robust controller design method is proposed to obtain a less conservative feedback controller and it is applied to a single-link flexible manipulator. The objective is to maximize the control performance guaranteeing the robust stability when regulating the tip position of the flexible manipulator in the presence of a large time-varying payload and parameter uncertainties such as stiffnes...

This paper investigates how to track a desired trajectory by a mobile manipulator that has redundant degrees of freedom (DOFs). Our approach is based on the analysis of its position and orientation. In the first part of the analysis, the manipulator contributes sub-vectors projected on the Z axis in the world frame, including position and orientation. In the second part, the mobile base and the...

A general framework for the feedback control of mobile manipulators is proposed. Its main originality lies in its capacity to address in a unified manner both cases of omnidirectional and nonholonomic mobile platforms. It also allows for the execution of the desired manipulation task without the manipulator colliding into its joint limits, whenever these two objectives are compatible. This is o...

This paper considers the nonlinear disturbance decoupling problem for a robotic manipulator that is mounted on a mobile platform. A mobile manipulation system offers a dual advantage of mobility offered by a mobile platform and dexterity offered by the manipulator. In this work, the tracking and nonlinear disturbance decoupling problems are studied with particular focus on disturbances due to u...

This paper proposes a fuzzy TSK controller to control a rotary flexible joint manipulator. The flexibility of joint is performed by means of a solenoid nonlinear spring, which is connected between actuator output and joint input in a bilateral connection form to transfer the produced torque; also the smooth model of frictions is used for modeling the dynamics of flexible manipulator. The effect...

Model based control schemes use the inverse dynamics of the robot arm to produce the main torque component necessary for trajectory tracking. For model-based controller one is required to know the model parameters accurately. This is a very difficult task especially if the manipulator is flexible. So a reduced model based controller has been developed, which requires only the information of spa...

In the article it is proposed to improve wave power plants by using a primary manipulator converter (PMC) with the structure of a parallel six-mobile manipulator for converting energy of waves into mechanical energy. There has been developed a physical model of a primary manipulator converter confirming its functionality. There have been obtained geometrical dimensions of a primary manipulator ...
