First, we will explain what the control system is a control system is a system provides the desired response by controlling the output this picture shows the simplified form of control system, One of the most interesting areas of control is engineering, because effective systems control requires systems to be properly understood, and the control engineer must also often look to control systems that are incomprehensible. The current challenge to control engineers is modeling and monitoring modern, complex and interconnected systems, it is also considered an important control system in modern technical society, in terms of control over simple machines and complex machines, the engineering control is part of our daily lives.
We can also consider a control system that is a device, or a set of devices that manages the behavior of other devices. A control system is a connection between connected or related components in a way that makes it command, route, or organize itself or another system.
The control system is a conceptual framework for systems design with organizational and tracking capabilities to give desired performance. For this, there must be a set of measurable signals for performance, another set of measurable signals to influence the evolution of the system in a timely manner and a third group that is not measurable but disturbs development.
The system is controlled by hand-held devices of modern systems and developed and used with newly overcome electrical and mechanical devices, and this hand can be used as a smart muscle to simulate muscle tissue, which means that this hand can work without large electronic devices that usually make artificial limbs not practical.
This system is used in computer control programs, music control programs, videos and many other things, but I will use it to move a wheelchair to help the disabled. I will explain this project as this project will make a quantum leap between man and machine. Where this machine will be working on the user commands, we can also say its human machine interface. Because there are many people with disabilities who find it difficult to move from one place to another, they have to ask someone to help the chair but with the wheelchair controlled manually, the disabled person is independent and does not need to ask anyone else to move his wheelchair. Only with the movement of his hand, the disabled person can move from one place to another without the need to help anyone who makes him dependent on himself.
In this project, a difficult technique is used to help disabled people who cannot move their fingers using precise control, which makes the disabled in the absence of any help from anyone.
The arduino output terminals are connected to the motor driver’s input (L293D) and the motor output is connected to a 2 motor DC input. This circuit is used to feed the project control circuit with the required power.
In this circuit the device will be connected Arduino UNO with Accelerometer sensor where that
Arduino is a single-board microcontroller meant to make the application more accessible which are interactive objects and its surrounding. The hard ware features with an open-source hardware board designed around an 8-bit Atmel AVR microcontroller. Current models consists a USB interface, 6 analog input pins and 14 digital I/O pins that allows the user to attach various extension boards.
In this circuit each pair of driver is a complete reflection motor H suitable for solenoid applications, the camp diodes must be used for high-speed exothermal output of the transient L293D, these diodes are combined to reduce system complexity and overall system size AV is separate from Vccz and the arduino is connected with buttery 5V the motor driver is connected to a 9V battery in order to operate the system.
CONTROL MACHINE USING HAND GESTUER, where this machine will be working on the user commands, we can also say its human machine interface. Because there are many people with disabilities who find it difficult to move from one place to another, they have to ask someone to help the chair but with the wheelchair controlled manually, the disabled person is independent and does not need to ask anyone else to move his wheelchair.
Because they are considered as suitable ideas for the level of the team in terms of possibilities, cost and programming to a large extent, The disabled face a great difficulty in movement, so if the disabled face a problem in moving the fingers too
Cost less / easy to use for Zoe
Using modern controllers and technology, where I will use DC motor Driver motor (L293D), arduino UNO and Accelerometer sensor, which will make this project easier to use for disabled people.
