A second-order non-linear discrete trajectory smoother is coupled with conventional control law for servo-control of permanent magnet synchronous motors (PMSMs). Conventional control relies on three closed loops with linear proportional-integral-derivative (PID) controllers and gives an undesirable performance under the mismatch. of system parameters and load conditions. To overcome this drawback, a discrete-time second-order non-linear trajectory smoother is applied for the control of a PMSM. The second-order non-linear trajectory smoother is a non-linear variable structure system (VSS) catering for smooth trajectory generation for a motion control system. The trajectory smoother guarantees robustness against a change of system parameters and load conditions. Simulation and experimental studies are included to demonstrate the effectiveness of the proposed control scheme.

Long Term Forecasting

The author’s vision of the problem of long-term forecasting in education is presented in the article. The modern education, going beyond the limits of class-lesson learning system is gaining more and more territory in direct and figurative meanings. Its non-linear trajectory of movement and rhythm is a process that occurs by the model of Dispars - the principle of nomadic vital activity. The author is of the opinion that only a combination of forecasting with strategic and indicative planning as in Foresight technology may in a certain extent contribute to the state regulation of the education system.
