摘要： Embodiments of the present invention provide improved accuracy of displacement control by using a multi-segment transformation of an actuator's non-linear response. The present invention may set intermediate points to effectively divide the actuator response into multiple segments. Each segment may be assigned a transform function that represents the actuator's response in that particular segment. The present invention may operate in two modes, a calibration mode and a normal operations mode. During calibration mode, the intermediate points and the segment transforms may be set. During normal operations mode, a drive signal may be generated according to the calibrated set values.

摘要： A drive signal for a motor-driven mechanical system has zero (or near zero) energy at an expected resonant frequency of the mechanical system. These techniques not only generate a drive signal with substantially no energy at the expected resonant frequency, they provide a zero-energy “notch” of sufficient width to tolerate systems in which the actual resonant frequency differs from the expected resonant frequencies.
摘要翻译： 在机械系统的预期谐振频率下，用于电动机械系统的驱动信号具有零（或接近于零）的能量。 这些技术不仅在预期谐振频率下产生基本上没有能量的驱动信号，它们提供足够宽度的零能量陷波，以容忍其中实际谐振频率与预期谐振频率不同的系统。

摘要： Embodiments of the present invention provide a drive signal for a motor-driven mechanical system whose frequency distribution has zero (or near zero) energy at the expected resonant frequency of the mechanical system. The drive signal may be provided as a pair of steps sufficient to activate movement of the mechanical system and then park the mechanical system at a destination position. The steps are spaced in time so as to have substantially zero energy at an expected resonant frequency fR of the mechanical system. The drive signal may be filtered to broaden a zero-energy notch at the expected resonant frequency fR.

摘要： Embodiments of the present invention provide a motor-driven mechanical system with a detection system to measure properties of a back channel and derive oscillatory characteristics of the mechanical system. Uses of the detection system may include calculating the resonant frequency of the mechanical system and a threshold drive DTH required to move the mechanical system from the starting mechanical stop position. System manufacturers often do not know the resonant frequency and DTH of their mechanical systems precisely. Therefore, the calculation of the specific mechanical system's resonant frequency and DTH rather than depending on the manufacturer's expected values improves precision in the mechanical system use. The backchannel calculations may be used either to replace or to improve corresponding pre-programmed values.

摘要： A drive signal for a motor-driven mechanical system has zero (or near zero) energy at an expected resonant frequency of the mechanical system. The drive signal may be provided in a series of steps according to a selected row of Pascal's triangle, wherein the number of steps equals the number of entries from the selected row of Pascal's triangle, each step has a step size corresponding to a respective entry of the selected row of Pascal's triangle, and the steps are spaced from each other according to a time constant determined by an expected resonant frequency of the mechanical system. Alternatively, the stepped drive signal may be provided as a series of uniform steps according to a selected row of Pascal's triangle, in which the steps are provided in a number of spaced intervals corresponding to the number of entries from the selected row of Pascal's triangle, each interval includes a number of steps corresponding to a respective entry from the selected row of Pascal's triangle and the intervals are spaced in time according to a time constant determined from the expected resonant frequency of the mechanical system. These techniques not only generate a drive signal with substantially no energy at the expected resonant frequency, they provide a zero-energy “notch” of sufficient width to tolerate systems in which the actual resonant frequency differs from the expected resonant frequencies.
