test1, test 2Abstract
Currently, fully automated rehabilitation robots can assist therapists in providing rehabilitation therapy. However, since the robot is totally automated, the patients could get hurt. On the other hand, manual treatment may cause less patient injury but it is tiresome, and there are not enough therapists in most countries. Power assist rehabilitation robots can support the therapists in conducting the treatment and may help to alleviate this problem. The goal of this study is to develop a control strategy for the robot to assist the therapist’s movement in a power assist upper limb rehabilitation treatment. The system combines the advantages of robotic and manual rehabilitation therapy. Torque and position sensors fitted on the power assist upper limb rehabilitation robot arm are used for motion intention estimation. The amount of angular velocity necessary to be delivered to the feedback controller will be determined by predicting the therapist‘s motion intention using the impedance control method. The resulting velocity from the motion intention estimator is incorporated into the Sliding Mode Control - Function Approximation Technique (SMC-FAT) based adaptive controller. The SMC-FAT based adaptive controller in the feedback loop, overcomes the uncertain parameters in the combination of the robot and the human arm. The motion intention estimator forecasts the movement of therapists. The proposed controller is used to regulate elbow flexion and extension motion on a power assist upper limb rehabilitation robot with one degree of freedom (DOF). The proposed control system has been tested using MATLAB simulation and hardware experimental tests. The outcomes demonstrate the effectiveness of the proposed controller in directing the rehabilitation robot to follow the desired trajectory based on the therapist's motion intention, with maximum errors of 0.002rad/sec and 0.005rad/sec for sinusoidal and constant torque values, respectively.
ABSTRAK: Pada masa ini, robot rehabilitasi automatik sepenuhnya boleh membantu ahli terapi dalam menyediakan terapi pemulihan. Walau bagaimanapun, disebabkan robot tercebat sepenuhnya automatik, pesakit boleh cedera. Sebaliknya, rawatan manual mungkin menyebabkan kurang kecederaan pesakit tetapi ia memenatkan, dan tiada ahli terapi yang mencukupi di kebanyakan negara. Robot pemulihan bantuan kuasa dapat menyokong ahli terapi dan boleh membantu untuk mengurangkan masalah ini. Sistem ini menggabungkan kelebihan terapi pemulihan robotik dan manual. Matlamat kajian ini adalah untuk membangunkan strategi kawalan untuk robot untuk membantu pergerakan ahli terapi dalam rawatan pemulihan anggota atas (tangan). Sistem ini menggabungkan kelebihan retapi pemulihan robotik dan manual. Alat pengukar tork dan kedudukan yang dipasang pada lengan robot pemulihan anggota atas digunakan untuk anggaran niat gerakan abli terapi. Jumlah halaju sudut yang perlu dihantar kepada pengawal maklum balas akan ditentukan dengan meramalkan niat gerakan ahli terapi menggunakan kaedah kawalan interaksi impedans. Halaju yang terhasil daripada penganggar niat gerakan dimasukkan ke dalam pengawal adaptif berasaskan Kawalan Mod Gelongsor - Teknik Penghampiran Fungsi (SMC-FAT). Pengawal penyesuaian berasaskan SMC-FAT dalam gelung maklum balas, mengatasi parameter yang tidak pasti dalam gabungan robot dan lengan manusia. Penganggar niat gerakan meramalkan pergerakan ahli terapi. Pengawal yang dicadangkan digunakan untuk mengawal lenturan siku dan gerakan lanjutan pada robot pemulihan dengan satu darjah kebebasan (DOF). Sistem kawalan yang dicadangkan telah diuji menggunakan simulasi MATLAB dan ujian eksperimen perkakasan. Hasilnya menunjukkan keberkesanan pengawal yang dicadangkan dalam mengarahkan robot pemulihan mengikut trajektori yang dikehendaki berdasarkan niat gerakan ahli terapi, dengan ralat maksimum masing-masing 0.002rad/s dan 0.005rad/s untuk nilai tork sinusoidal dan malar.
