The upper limb disability experience includes both the loss of functional skills as well as a hand's sensation. Sensation ability, it's very important to human experience and helps him to reach a good interaction with surrounding. Also, Feedback from robot arm is very important for understanding the protection for the robot arm and providing contact between human and arm. Research studies to regain sensation through many technics This paper proposed a heat sensation system, this system transfers the heat at the end of each robot arm finger to a specific position. The heating pad is used to generate similar temperature at fingers. System sensation was tested and evaluated to reach the desirable response. The results show the ability of the system to transfer temperature on a healthy position at handicapped.
Hardware-description Language (HDL) is typically used to synthesise the digital hardware of the control systems. Importantly, this requires a deep knowledge in digital hardware design; howeverthis is not essential for the design of the real time control systems. From this prospective, there is a great interest to employ a modern environment tool to simulate, design, validate and to rapidly implement the hardware to the target of the application. For this reason, this paper aims to presentthe methodology and effectiveness of using the LABVIEW-FPGA toolin embedded system design of digital control algorithms. As the model of the control system has been already simulated using the LABVIEW environment, therefore this will shorten the time of hardware implementation, where the designed control algorithm will directly translate into hardware resources by using LABVIEW-FPGA module. The methodology of hardware digital controller design is clearly explained using LABVIEW-FPGA modulebased SPARTAN-3EFPGA from Xilinx. The prototyped temperature control system using (CI-53003) is accommodatedas one of the examplesto demonstrate the embedded hardware design of digital control system. Experimental results clearly show the successful hardware implementation of the designed algorithm.
This paper presents a real time self-tuning controller for DC motor system. Pole-placement adaptive controller based on Exponentially Recursive Least Square (ERLS) algorithm is proposed. The parameters of the DC motor are estimated using ERLS algorithm. Once the estimation error is minimized, the identified parameters are forward to the supervisory control unit to find the corresponding PID gains. A PCI-6251 data acquisition card from National Instrument (NI) and the prototyped control system (33-100 & 33-110) from feedback device are deployed for real time implementation of the proposed solution. Simulation and experimental results verified the effectiveness of the ERLS algorithm, where the parameters of DC motor are estimated rapidly and accurately. Results, also shows the validation of the proposed self-tuning controller for position control of the DC motor system. General TermsControl Algorithm.
