IMPROVED PI CONTROL VIA DYNAMIC INVERSION

Improved Pi Control via Dynamic Inversion

Abstract: In this paper we present a new design methodology to achieve high performances in the setpoint following task by means of a standard Proportional-Integral (PI) controller. In particular, a dynamic inversion procedure is adopted to synthesize a suitable command input to the closed-loop control system. In this way, the PI parameters can be selected for a load rejection purpose, as the d...

PI(D) tuning for Flight Control Systems via Incremental Nonlinear Dynamic Inversion

Previous results reported in the robotics literature show the relationship between time-delay control (TDC) and proportional-integral-derivative control (PID). In this paper, we show that incremental nonlinear dynamic inversion (INDI) — more familiar in the aerospace community — are in fact equivalent to TDC. This leads to a meaningful and systematic method for PI(D)-control tuning of robust no...

Inertia-Independent Generalized Dynamic Inversion Spacecraft Control

The generalized dynamic inversion control methodology is applied to the spacecraft attitude trajectory tracking problem. It is shown that the structure of the skew symmetric cross product matrix alleviates the need to include the inertia matrix in the control law. Accordingly, the proposed control law depends solely on attitude and angular velocity measurements, and it neither requires knowledg...

Excitation Control of Synchronous Machine Using Dynamic Inversion Control

Excitation control of synchronous machine is done in order to keep the terminal voltage constant. This paper describes the advantage of using a nonlinear technique called Dynamic Inversion (DI) in order maintain the voltage at the terminals constant. An excitation model which includes the excitation system stabilizer (ESS) and the transient gain reduction (TGR) blocks is considered. The referen...
