The mobility of people who have had a lower limb amputated is slower, less stable, and needs more metabolic energy than the movement physically fit, also, often difficulty moving on uneven terrain stairs. In most cases, these problems may be traced back to usage controllers for an above-knee prosthesis, which enhances quality life millions individuals lost limbs. this work addresses dynamic mod...

The brushless direct current (BLDC) motor is characterized by high torque, which made it widely used in many industrial applications. To improve the working performance of BLDC motor, addition controllers such as proportional integral derivative (PID) adopted. obtain high-performance controllers, design process adopted to develop a suitable algorithm. genetic algorithm (GA) was chosen tune PID ...
