In this chapter, we will contextualize ADRC to deliver interpretations from the established field of linear control systems. This will, firstly, involve an interpretation of ADRC in terms of existing state-space control approaches. Secondly, a transition to the frequency domain is being made, as a major part of practical control engineering is performed in this domain. Analyzing and understanding ADRC from a frequency-domain perspective allows for a much easier migration from the PID world of controllers.

摘要

In this chapter, we will contextualize ADRC to deliver interpretations from the established field of linear control systems. This will, firstly, involve an interpretation of ADRC in terms of existing state-space control approaches. Secondly, a transition to the frequency domain is being made, as a major part of practical control engineering is performed in this domain. Analyzing and understanding ADRC from a frequency-domain perspective allows for a much easier migration from the PID world of controllers.
