A measuring method of hip and knee joint angles based on omni-directional lower limb rehabilitation platform is proposed. Several ultrasonic modules are vertically fixed inside the rehabilitation platform, the relative distances between the ultrasonic modules and surface of each lower limb are detected circularly in walk process, hip and knee joint angles at any time are obtained according to the...
In this paper, an ultrasonic gait detection and analysis method is introduced. The proposed detection system, which is fixed on an omni-directional lower limb rehabilitation robot, can get the gait parameters of subjects including step length, speed, and frequency, etc. A set of gait symmetry index is proposed to analysis walking symmetry of subjects, which is based on gait cycle phase, swing instantaneous...
Reactive and harmonic current produced by electric railway seriously affects the power quality of power supply system. Based on the electric railway practice, this paper designed a shunt method in the side of voltage 27.5kV to solve reactive and harmonics current problem. Study a high-performance control method of cascade single phase STATCOM, which includes modulating signal calculation, individual...
For the Fuel Cell Engine, the air compressor driving motor is controlled by high frequency inverter system. Because of the period interruption caused by commutation and limitation of the switch frequency, there are more harmonic components in inverter during high frequency region. In this paper, harmonic analysis and simulation are presented in different voltage modulation techinques. The simulation...
Rehabilitation robot is a type of assistant recovery equipment designed particularly for the sick people having difficulty in walking to get gait rehabilitation training, the research on joint flexibility is of great significance for the program making of walking gait control. The three closed-loops PID control method was proposed for the lower-limb rehabilitation robot MACCEPA (mechanically adjustable...
The paper proposes an obstacle-avoidance control algorithm based on the fuzzy matching of obstacle environment. The algorithm is mainly used in the obstacle-avoidance control of omni directional lower limbs rehabilitation robot. The method generates the eigen value of obstacle environment using detected angle information of obstacle boundary, and fuzzy matches with the known environment information...
In this paper we describe the design and evaluation of a passive lower limb assistive exoskeleton based on omnidirectional rehabilitation vehicle. According to the leg dynamics during assisted walking, we optimize the design parameters to make the lower limb obtain the most positive energy. We employ MACCEPA (mechanically adjustable compliance and controllable equilibrium position actuator) in design...
This paper focuses on adaptive velocity compensation along state axis aiming at dent and friction force ripples using parameterized iterative learning control (ILC) for permanent magnet linear synchronous motor (PMLSM) executing same control instruction repeatedly. Velocity ripples are primarily attributed to periodic disturbances such as dent force and the gliding friction in PMLSM. The dent force...
The design and implementation of an omnidirectional lower limbs rehabilitative training robot are described. The robot is designed to improve patient's locomotion, who suffers from impairment in walking ability after neurology injuries. The robot is characterized with three key points as following: 1) a wheeled mechanical structure, 2) gait phase analysis system using wearable press sensors and 3)...
