A torque control system is configured to automatically determine the fully open position and fully closed position of the valve without the need of manual operation of the valve. In addition, a control unit of the torque control system can obtain a control parameter based on a driving device operation signal detected by a detection unit, and output a control command to a driving unit to change an operation parameter of the driving device, so that the torque applying by the driving device on the valve can be adjusted, therefore the torque control system of the present application can accurately output the operating torque required by the valve, so that there is no circumstances that the operating torque is too large to damage the valve or the operating torque is too small to be unable to drive the valve.

A convertible power tool that can operate in first and second configurations. The tool includes a base unit configured to receive at one time either a first module or a second module. The different modules provide for different levels of functionality. The first module includes one or more components that provide for a first level of functionality. The second module includes one or more components that provide for an advanced second level of functionality. Each of the base unit and first and second modules may include interfaces that provide for physical engagement as well as power/data engagement. In use, one of the first and second modules is connected to the base unit to provide for the desired functionality incorporated with the tool. The tool may also be reconfigured by removing the attached module and replacing it with the other module thus providing for a different functionality level.

This document describes systems and methods for controlling an exoskeleton. The system receives a measurement of a first torque applied to a rotational joint coupling a first component to a second component, the first torque being applied by a motor via a cable. The system determines, based on the measurement of the first torque, a first portion of a second torque to apply to the rotational joint. The system determines, based on the measurement of the first torque, a second portion of the second torque to apply to the rotational joint. The system determines a value of the second torque to apply to the rotational joint based on the first portion and the second portion. The system controls the motor for applying the second torque to the rotational joint via the cable.

A servo control apparatus includes a velocity command creation unit; a velocity detection unit; a velocity control gain; a torque command creation unit; a filter configured to attenuate a particular frequency band component in a torque command value; a sine-wave sweep input unit configured to perform a sine-wave sweep in a predetermined frequency range; a frequency characteristics calculation unit configured to calculate a frequency characteristic of a sine-wave; and a filter adjustment unit configured to attenuate a particular frequency band component in a torque command value. A signal is input to the velocity control gain. The signal is obtained by adding a sine-wave to a difference between a velocity command value and a velocity detected. The filter adjustment unit measures an influence of the velocity control gain on a resonance frequency and resonance peak amplitude, while changing a value of the velocity control gain, thereby adjusting the filter.
