Advanced speed control (observer)

The phase shifts over time in the feedback branch generate high-frequency noise as well as high-frequency resonances.
The single-mass observer reduces these high-frequency interference and increases the control dynamism.
The function of the observer is based on the mathematical description of the controlled system which calculates the trend over time of the state variables under the influence of the input variables. The difference between the measured and estimated state variables is fed back to the estimated state variables by way of a feedback matrix, parameter P 0353(1) "Observer time constant". The aim is to equalize the estimated state variables as quickly as possible to the measured variables.
