In the article the automatic drive positioner technology systems increased speed and accuracy on the basis of multi-parameter sensor rotor (MPMD). The proposed scheme, technical solution (MPMD) with improved integral evaluation of several parameters of positional displacement control objects. The generalized mathematical model of the sensor actuator position struktre. Computational experiments by the Runge-Kutta in the environment of the program Matlab-simulink are obtained depending on the basic parameters of an actuator position. When you perform a typical positional cycle The influence of the major geometric, hydraulic and thermodynamic characteristics of the expiry of the compressed air through the nozzle sensor element on its expenditure-Perepadnaya response. It is found that the maximum deviation does not exceed 5% of the reference sensor. This will improve the accuracy of parameter estimation process of positioning and formation of control actions in real space and time.

In this paper is offered hydraulic sensor to measure the kinematic, power and energy parameters. Developed scheme and the principles of the hydraulic sensor. Identification on the special flow lab with real modes of the device is determined by its performance in different conditions. Approximation of the results received dependences flow and pressure drop characteristics on the speed and entrance pressure, allowed more correctly assess and describe the operation of the hydraulic sensor over the entire range of speed and entrance pressure.
