This paper is concerned with the design of a fault estimation scheme with component fault and sensor noise for the three-phase inverter of high-speed trains. To design the component fault estimation observer, the three-phase inverter system states are augmented with the disturbance treated as new states, leading to an augmented and singular system. The observer is designed to generate the needed residual...
This paper proposes an incipient sensor fault detection method for three-phase PWM inverter devices in electric railway traction systems. An adaptive and sliding mode unknown input observer is designed for sensor faulty inverter system. The invariant ellipsoid is used to generate threshold. The parameters of the observer are particularly designed such that the estimation errors converge to the threshold...
Research on robot control and related technology of biped walking has important theoretical value in the field of robot research. Comparing the advantages and disadvantages of existing robot control and walking schemes, this paper designs and implements a biped walking robot under the control of Cortex-M3. By studying and emulating human walking gait, we designed a robot which can walk in the way...
