In this paper, a comparative analysis of Hybrid Sliding Mode PI and classical PI with intelligent properties controllers for Ni-Ti SMA smart actuator position control is presented. The SMA actuator mechanical dynamics are obtained using one-way actuator model. The actuator returns to its initial position using bias spring force. The SMA material model using the shear-strain driven approach is discussed. Two different controllers are presented and compared as a SMA actuator position controllers. The Hybrid Sliding Mode PI and the classical PI with intelligent properties controllers are compared. The comparison results depict that the controller with intelligent properties advantages surpass the advantages of the Hybrid Sliding Mode PI controller and it improves the rising and settling times of output displacement response. Both controllers provide output displacement without overshoot and zero steady state error which are essential in smart actuators applications. © 2019 IEEE.

A Stability Analysis Based on Dissipativity of Linear and Nonlinear Repetitive Control

引用

IFAC-PapersOnLine 2019年第2期52卷 40-45页

作者： Federico Califano Alessandro Macchelli Robotics and Mechatronics Lab University of Twente The Netherlands Dept. of Electrical Electronic and Information Engineering (DEI) University of Bologna Italy

This paper deals with repetitive control (RC). More specifically, a parametrised version of the repetitive compensator, i.e. of the infinite-dimensional controller employed in RC schemes, modelled as a boundary control system (BCS) in port-Hamiltonian form is presented. Well-posedness and stability of such control scheme are rigorously addressed thanks to novel tools based on dissipativity theory and originally developed for the stabilisation of BCS. Here, the linear and the nonlinear cases are tackled, and in both the cases the classes of plants for which RC schemes are exponentially stable are determined. Moreover, and explicit motivation of perfect asymptotic tracking and disturbance rejection for exponentially stable RC systems without relying on the internal model theory is provided. To show the validity of the analysis, simulations are reported.

The article is devoted to mathematical modeling of large (geometrically nonlinear) deformations and displacements of rubber-like materials and metal alloys. It is shown that the Cauchy's tensor equally correctly describes the transformations for large, small, and infinitesimal values of gradients. A new approach to the formulation and solution of boundary value problems of statics is proposed. A mathematical model has been developed to analyze the stress-strain state of various structures. Developed computer programs calculate and build virtual graphs of transformations of various bodies under load and can be used when students study various sections of the mechanics of a deformable solid body.

International Conference on robotics and Artificial Intelligence (ICRAI)

作者： Muhammad Bilal Ali Raza Mohsin Rizwan Muhammad Ahsan Hafiz Farhan Maqbool Syed Abbas Zilqurnain Naqvi Al-Khawarizmi Institute of Computer Science UET1 Lahore HCR2 Lab National Center of Robotics and Automation Lahore Pakistan Dept. of Mechatronics & Control Engineering National Center of Robotics and Automation Lahore Pakistan Dept. of Mechatronics & Control Engineering UET Lahore Lahore Pakistan

The central aim of this research is to propose a solution to rehabilitate historic places using a robotic manipulator. In this pursuit, the objective is to clean flat or curved surfaces of mihrab/muqarnas and to write lost Arabic inscriptions on spandrel using 7 Degree of freedom (DOF) robotic manipulator. Inverse kinematics solution for 7 DOF is derived by fixing redundant joint and solving the remaining 6 DOF inverse kinematics. Image processing techniques are used to get data from the given image for the robotic calligraphy operation on the spandrel to restore the lost inscriptions. Path planning exercise is implemented to navigate the end-effector on the desired path to write lost inscriptions and to clean curved surfaces of muqarnas. Proposed solutions are verified by simulation using MATLAB. The results showed that the manipulator successfully tracked the given path to perform the desired operation in mihrab as well as calligraphy operation on spandrel.

This paper proposes a new quadratic V/f-based control of a PV induction motor driven water pumping system without storage batteries. The system consists of PV array, DC-DC boost converter, voltage source inverter (VSI), induction motor, and water pump. In order to extract the maximum power from the PV array, the incremental conductance (INC) method is simply utilized. The dc-link voltage is maintained constant using a proportional-integral (PI) controller by controlling the induction motor speed using simple open loop quadratic scalar V/f control. The proposed quadratic scalar V/f control is compared with the widely used linear V/f control using a simulation case study based on MATLAB/SIMULINK . The performance of the proposed method is examined under variable values of solar radiation. When compared with the available scalar controllers, the proposed controller generally improves the system dynamics as well as the overall system efficiency especially under low speed (low discharge) operation. The simulation results have proved that the system output power and the corresponding overall efficiency have been approximately doubled under low speed operation.

A new interconnected manipulator whose end-effector can carry out 3 translational motions in the 3D space with constant orientation is presented in this paper. It is the only interconnected manipulator in the world that produces such motion, which is needed for many industrial applications, using solely rotary actuators and joints. Practically, rotary actuators and joints are preferable than linear actuators and joints because of their cheaper cost, smaller installation size and better reliability. The unconventional interconnected structure of the proposed manipulator enables it to possess, to some extent, the combined advantages of serial and parallel manipulators such as light weight, high speed, rigidity and accuracy as well as large workspace to size ratio. The mechanism description, mobility analysis, kinematic analysis and workspace analysis are presented in details. Finally, an accurate simulation using ***© software is carried out to demonstrate the feasibility of the proposed manipulator's design. © 2018 IEEE.

Path bundling, a class of path planning problem, consists of compounding multiple routes to minimize a global distance metric. Naturally, a tree-like structure is obtained as a result wherein roots play the role of coordinating the joint transport of information, goods, and people. In this paper we tackle the path bundling problem in bipartite networks by using gradient-free optimization and a convex representation. Then, by using 7,500 computational experiments in diverse scenarios with and without obstacles, implying 7.5 billion shortest path computations, show the feasibility and efficiency of the mesh adaptive search. © Copyright 2017 by SCITEPRESS - Science and Technology Publications, Lda.

Thin coatings for pumping station mechanical components

IOP Conference Series: Materials Science and engineering 2019年第1期591卷

The pumping stations are key points of water treatment plants, their performance directly affecting the serviceability of the entire water treatment system. The excessive wear of mechanical components conducts to pumping station out of service state. The deposition of thin coatings on the elements subjected to wear can generally extend the operating time of the water treatment plants. The paper analyses the failure modes of the mechanical components of the pumping stations and the existing efficient solutions for thin coating deposition to protect them from excessive wear. Consequently, an effective coating is deposited on the raw metal by Atmospheric Plasma Spraying (APS) and tribological tests are developed for an initial assessment of the anti-wear properties of the coating. The worn contact surfaces are analysed by Scanning Electron Microscopy (SEM) and the chemical composition is established by Energy-dispersive X-ray spectroscopy (EDS). The tests are still in development, revealing that the main failure modes of the coating are abrasive wear and delamination. Future research will be conducted to identify the best combination of powders for a multiple layer deposited coating with high wear resistance.
