A speed tracking control method for induction machine is shown in this paper. The consists of outer loop and inner current loop. Model predictive without the need calculation weighing factors utilized loop, which generates a continuous set voltage reference values that can be modulated applied by inverter to machine. Interesting parallels are drawn between developed state feedback principles he...

This paper presents a force sensorless workspace hybrid position/force control method with equivalent mass matrices switching for rubbing motion. The express an interference between axes. Since the determinant of matrix computed from design values robots becomes near zero around singular configuration robots, utilized are often arbitrarily designed. However, inappropriate conditions deteriorate...

sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...

Independent gear-shifting actuation systems, which are based on linear electromagnetic actuators (LEMAs), have tremendous potential to minimize the shifting duration of automated mechanical transmission (AMT). A velocity estimator based on the measurements of current is designed to achieve sensorless control of the actuator by using only electrical subsystem, thus avoiding the use of a complete...

Power Assist Wheelchair (PAW) has being developed for users and caregivers in current high aging society. As a human-machine system, it is important for PAW to sense the human force and operation. In this paper, a Disturbance Observer (DOB) based force estimator is applied to PAW to estimate external forces including the human force, the rolling resistance and the sliding resistance. The rollin...
