An asymmetric PI (aPI) controller based on a control algorithm, which is the modification of the PI control method, has been suggested. The principal characteristic feature of the aPI controller is that different values of proportional and integral constants are used at positive and at negative errors. Contrary to the classical PI controller, the proposed controller allows us to improve the positive disturbance rejection of control systems without sacrificing the unit step response dynamics. Results of the investigation of the concrete control systems based on the aPI controller are also presented. Using the dynamic system simulation program Simulink performed the investigation.

“…The AC induction motor drive supplied by the frequency converter becomes a variable speed drive and is used for the control of technologies and machines. The present-day frequency converter is a highly sophisticated device, which allows the manual control of motor rotation speed, automatic control according to the signals of an appropriate sensor [1,2] or computer-based control. The frequency converters usually utilize a converter-inverter structure as shown in Fig.…”

A model of the AC induction motor, which allows us to analyze all operation modes of motor supplied by the frequency converter, has been developed. A simulation of the inverter of the frequency converter and the AC induction motor interaction on the basis of the developed motor model, using software MATLAB, was performed and a motor regenerative braking mode was investigated. The results of investigation are used for the development of fault protection of the inverter.

The method of creating the dynamical model of the CNC gear hobbing machine and for its analyzing is presented in this paper. The model comprises detail mechanical parts of the hob spindle and work spindle axes, their electrical counterparts, linking, and allows one to investigate dynamic characteristics of the machine and to simulate processes, which take place during gear hobbing. The article also presents the simulation diagram, introducing these axes and the third axis, which help to model the cutting process. It also presents results of simulation of processes during hobbing and amplitude-frequency characteristics calculated.
