A new control system of a hand gesture-controlled wheelchair (EWC) is proposed. This smart control device is suitable for a large number of patients who cannot manipulate a standard joystick wheelchair. The movement control system uses a camera fixed on the wheelchair. The patient’s hand movements are recognized using a visual recognition algorithm and artificial intelligence software; the derived corresponding signals are thus used to control the EWC in real time. One of the main features of this control technique is that it allows the patient to drive the wheelchair with a variable speed similar to that of a standard joystick. The designed device “hand gesture-controlled wheelchair” is performed at low cost and has been tested on real patients and exhibits good results. Before testing the proposed control device, we have created a three-dimensional environment simulator to test its performances with extreme security. These tests were performed on real patients with diverse hand pathologies in Mohamed Kassab National Institute of Orthopedics, Physical and Functional Rehabilitation Hospital of Tunis, and the validity of this intelligent control system had been proved.

Tongue Motion

A new intelligent powered wheelchair is urgently needed for the individuals with tetraplegia and similar impairments who are unable to use the standard joystick. Based on the tongue motion detection, a new control system is introduced in this paper which is helpful for users to operate powered wheelchair efficiently and easily. This article introduces two control modes, including tongue motion control mode and infrared control mode. Wherein the infrared control mode mainly use the infrared controller. The tongue motion can be detected with several vibration film sheets that were embedded in the headset and a standard analog signal can be generated with embedded controller to control the wheelchair. The tongue motion drive system integrated into headset was developed and the control of the wheelchair has been tested moving along the designed route. Preliminary results show that the system is simple and convenient to control powered wheelchair with low cost, which has potential application in intelligent control domain.

With the rapid development of the Internet, the remote control technology was demanded more. In this paper, we designed a simple and practical remote intelligent control system, using CGI technology to complete the construction of Web servers and embedding uCOSII as the real-time operating system in Cortex-M3 core processor. By porting TCP/IP protocol stack, users could login in the server to access and control the system via the Internet. Using NRF2401 wireless technology to build a terminal network, the terminal carried out intelligent control with field data collected by sensors. Meanwhile, users could make monitor and control on a control terminal via a Web browser on a PC or mobile. The remote intelligent control system was stable, real-time, low cost, fit for the smart home, industrial remote monitor and so on, so it would have a better application prospects.

Despite the diversity of electric wheelchairs, many people with physical limitations and seniors have difficulty using their standard joystick. As a result, they cannot meet their needs or ensure safe travel. Recent assistive technologies can help to give them autonomy and independence. This work deals with the real-time implementation of an artificial intelligence device to overcome these problems. Following a review of the literature from previous work, we present the methodology and process for implementing our intelligent control system on an electric wheelchair. The system is based on a neural algorithm that overcomes problems with standard joystick maneuvers such as the inability to move correctly in one direction. However, this implies the need for an appropriate methodology to map the position of the joystick handle. Experiments on a real wheelchair are carried out with real patients of the Mohamed Kassab National Institute Orthopedic, Physical and Functional Rehabilitation Hospital of Tunis. The proposed intelligent system gives good results compared to the use of a standard joystick.

Open loop control system is the type without feedback, that is, no sensor sensing the control variable, hence works on time basis. The paper established the facts that the system will prevent ubiquitous fire incidences associated with electric stoves and other heating devices. It describes the application of simple electronics circuitries in designing the low cost Cooker Control Device. The building blocks of the unit were designed one after the other using preferred components available in the local markets. The project was wired on Breadboard. The board permits the design to be tested without employing soldering processes. The design enumerates some important construction precautions which are further accentuated with the inclusion of various tips on healthy soldering processes. It is believed that the unit will prevent fire incidences associated with electric cooker. Simple explanations given to drive home power electronics principles used and copious illustrations rendered will make the innovative and ingenuous enterprise interesting to power electronics enthusiasts and other professionals alike. The paper recommends incorporation of embedded system with Liquid Crystal Display in the future design improvement.

The use of a communication network in the closed loop control systems has many advantages such as remotely controlling equipment, low cost, easy to maintenance, efficient information transmission, etc. However, the Networked Control System (NCS) has many drawbacks, such as network-induce end-to-end time delay and packet loss, which lead to significant degradation in controller performance and may result in instability. Aiming at solving performance degradation in NCS, this paper propose to take the advantages and strength of the conventional Proportional-Integral-Derivative (PID), Fuzzy Logic (FL), and Gain Scheduling (GS) fundamentals to design a Fuzzy-PID like-Gain Scheduling (F-PID-GS) control technique, which has been proved to be effective in obtaining better performance. The True Time toolbox is used to establish the simulation model of the NCS. Ethernet as a communication network is simulated for different load conditions and random packet loss. The design approach is tested on a second order stepper motor. The results obtained show the effectiveness of the proposed approach in improving the overall system performance.
