Directional change and windup phenomena in LQR-controlled systems with actuator failure

Horla D.

Archives of Electrical Engineering

2018

Vol. 67, nr 2

345–-359

The paper presents a phenomenon of directional change in the case of a LQR controller applied to multivariable plants with amplitude and rate constraints imposed on the control vector, as well as the impact of the latter on control performance, with the indirect observation of the windup phenomenon effect via frequency of consecutive resaturations. The interplay of directional change of the computed control vector with control performance has been thoroughly investigated, and it is a result of the presence of constraints imposed on the applied control vector for different ratios of the number of control inputs to plant outputs. The impact of the directional change phenomenon on the control performance (and also on the windup phenomenon) has been defined, stating that performance deterioration is not tightly coupled with preservation of direction of the computed control vector. This conjecture has been supported by numerous simulation results for different types of plants with different LQR controller parameters.

Directional change in multivariable LQG control with actuator failure

Horla D.

Bulletin of the Polish Academy of Sciences. Technical Sciences

2017

Vol. 65, nr 4

419--428

The paper presents the phenomenon of directional change in LQG control of multivariable systems with amplitude constraints, as well as the impact of the latter on control performance. The interplay of directional change of the computed control vector with control performance has been thoroughly investigated, and is a result of the presence of constraints imposed on the applied control vector for different proportions of the number of control inputs to plant outputs. The impact of directional change phenomenon on the control performance has been defined, stating that performance deterioration is not tightly coupled with preservation of direction of the computed control vector. The statement has been supported by numerous simulation results for different types of plants with different LQG controller parameters.

Optimised conditioning technique for a priori anti-windup compensation

Horla D.

Systems Science

2008

Vol. 34, no 3

67-73

The paper presents discussion over two new optimal conditioning technique algorithms for a priori anti-windup compensation in the case of multivariable systems with amplitude- and rate-constrained control vector together with requirement of no directional changes in controls.

Directional change for rate-constrained systems with anti-windup compensation

Horla D.

Systems Science

2008

Vol. 34, no 1

49-58

The paper presents a problem of directional change in controls when anti-windup compensator is introduced into the control system, together with presenting connections of anti-windup compensation and avoiding changes in control vector direction for systems with amplitude and rate constraints.
