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.
Highlights
Controlling a non-stationary object is rather challenging because it is quite difficult to predict in advance at what moment and by what value the parameters of the test object will be subject to change
The work proposes a new approach to controlling non-stationary objects, which requires the use of a controller in the automatic control system
The controller consists of one proportional and one differential element, and an integrating link based on the Clegg integrator [1]
Summary
Controlling a non-stationary object is rather challenging because it is quite difficult to predict in advance at what moment and by what value the parameters of the test object will be subject to change. One of them implies calculating new coefficients for the controller when changing parameters of the test object. The work proposes a new approach to controlling non-stationary objects, which requires the use of a controller in the automatic control system. The controller consists of one proportional and one differential element, and an integrating link based on the Clegg integrator [1]. It is supplemented with a pseudo-linear correcting device with phase advance [2].
