Control of the movement and positioning are the most intensive tasks of automatic control and regulation. However, these problems must be solved in the automation objects such as assembly and production lines, manufacturing machines, conveyors, hoisting machines, packaging machines, filling lines for liquids, metal-working machines. One problem lies in the fact that all the real drives are connected to the actuators with not perfectly tough shafting, but has some elasticity. This leads to the difficulty of motion of the executive body of the drive automatic control systems which consists of signal source generating signal due optimum speed diagrams for small movements of electric drive’s actuating device and automatic regulation system, which allows to work out optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision. In this article were developed optimum speed diagram for small movements of ultra-precise electric drive with elastic shafting. Were have identified all parameters of diagrams and its range of existence and also developed a device for generating the optimum speed diagram for small movements of ultra-precise electric drive with elastic shafting. The implementation of the proposed hardware software complex will significantly improve the accuracy of motion actuators of various ultra- precise DC drives

One problem lies in the fact that all the real drives are connected to the actuators with not perfectly tough shafting, but has some elasticity. This leads to the difficulty of motion of the executive body of the drive automatic control systems which consists of signal source generating signal due optimum speed diagrams for medium movements of electric drive’s actuating device and automatic regulation system, which allows to work out optimum speed diagrams for medium movements of electric drive’s actuating device with ultra-precision. In this article were developed optimum speed diagram for medium movements of ultra-precise electric drive with elastic shafting. Were identified all parameters of diagrams and its range of existence. Also developed device for generating the optimum speed diagram for medium movements of ultra-precise electric drive with elastic shafting.

The time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed has been designed. The algorithm has been developed to determine the parameters of the time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed. The region of existence of the time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed has been set. According to the results of the numeral experiment, the dependences of the duration of the cycle of movement of the executive body of the drive from prescribed displacement (rotation angle) for different values of the fifth derivative of the speed have been plotted
