Control levers for command setting are widely used, e. g. as thrust control in marine or aviation applications. Actually these levers are equipped with a mechanical brake to avoid movements of the lever in case of vibrations. Special control points are indicated to the user by mechanical detents. The basic idea of an active lever is to create a force feedback to the user which depends on the current...
This paper presents the intelligent control schemes for PM spherical stepper motor under the discrete stepping mode and continuous tracking mode. In the discrete stepping mode, a fuzzy inference system is used to predict the rotor orientation and perform the activation operation. Based on the non-linear system dynamic model under continuous trajectory tracking mode, the model reference adaptive control...
This paper presents three control schemes for PM spherical stepper motor drive. In the neural network PD control scheme, the neural network is used to train the control parameters online. Based on the non-linear system dynamic model under continuous trajectory tracking mode, the robust neural network control scheme is presented to eliminate uncertainties to improve the trajectory tracking robust stability...
There are many uncertainties and disturbances in real dynamics system of spherical stepper motor that make traditional control methods with lower precision. Based on the non-linear system dynamic model under continuous trajectory tracking mode, the robust neural network control scheme is presented to eliminate uncertainties to improve the trajectory tracking robust stability and overcome the undesired...
