Pseudo-linear correction as a means of improving the quality of control systems

Abstract

The work shows the possibility to improve the quality of automatic control systems by applying the controller which includes a pseudo-linear correcting device with phase advance, one proportional and one differential element and an integrating link based on the Clegg integrator. The conducted research shows that such approach to constructing automatic control systems enables to improve significantly the performance indices for transient processes when controlling objects whose parameters change their values over time. The work concludes that the use of such systems is possible and appropriate for non-stationary objects when changing their parameters in quite a wide range.
