摘要： A command trajectory drives a stage to produce a smooth motion while minimizing any vibrations or oscillations of the structure. The command trajectory provides an acceleration and a deceleration that have derivatives, known as the jerk, equal to zero at the beginning and end of the acceleration and deceleration periods. Because the jerk is equal to zero at the beginning and end of acceleration and deceleration, the influence of the reactive forces on the positioning system's structure is reduced, thereby minimizing oscillation of the structure. Moreover, the jerk is continuous throughout the acceleration and deceleration periods, resulting in a smooth continuous motion of the stage. The jerk on the stage during acceleration and deceleration has an adjustable duration to reduce the structural disturbances and decrease settling time.

摘要： A tan having a fan wheel and an electric motor driving it, and a control unit for controlling the motor output as a function of fan-specific parameters. An actual-value signal corresponding to an actual rotational speed of the fan is measured and compared with a control signal corresponding to a required speed, and the actual speed is adjusted to the required speed by means of the control unit, wherefore the actual speed and the actual motor current or supply current are measured and conducted to a microcontroller as input signal variables, whereby the fan-specific data such as wheel diameter, density of the conveying medium, fan coefficients, motor coefficients, and a preset artificial characteristic curve ps=ƒ({dot over (V)}s ) are stored in the microcontroller as default values. The microcontroller generates the required-speed signal, which is a function of the electrical current variables and the actual speed, based on the preset artificial characteristic curve ps=ƒ({dot over (V)}s) where ps=required operating pressure and Vs=required volume flow.

摘要： Disclosed is an optimized brake method for braking a motor rotating at a high speed. When the motor rotates at the high speed, the present invention reduces the rotation speed of the motor using a mechanical brake method which has a relatively high rate of energy exhaustion, and when the rotation speed of the motor reduces below a predetermined speed, the present invention stops the motor using an electrical brake method. Therefore, since the mechanical brake method is used during the high speed rotation interval, heat occurrence can be prevented, and the electrical brake method is used during the relatively low speed interval so that the motor can be stopped within a short time.
