System Types in Feedback Control With Saturating Actuators

IEEE Transactions on Automatic Control, 2004
This paper extends the classical notation of system type to feedback control with saturating actuators. For step, ramp, and parabolic inputs, it defines the so called trackable domains and evaluates steady state errors. It shows that, unlike the linear case, the role of the poles at the origin of the plant and the controller are different and, on this ...

Design of Actuator Saturation Compensators for Absolute Stability

IFAC Proceedings Volumes, 1995
Abstract Actuator saturation is a common problem in practical control systems. Existing saturation compensation schemes are often derived with little consideration for the stability of the closed-loop system. An approach to design a compensator for a given system such that the compensated system is absolute stable is presented.

Stability of Fuzzy Controllers Subject to Actuator Saturation

IFAC Proceedings Volumes, 1997
Abstract In this paper, the compensation of a closed-loop system with fuzzy control subject to actuator saturation is discussed. Condition for global stability of the compensated system is derived using a Lyapunov function based on the fuzzy model proposed by Takagi and Sugeno. Example is presented to illustrate the result.

Sampled-Data Control with Actuators Saturation

2016
With the rapid development of intelligent instrument and digital measurement, modern control systems tend to be controlled by digital signal processing approaches, i.e. the control input signals are kept constant via a ZOH during the sampling instants and are only allowed to change at the discrete time instants.

Manual flight control with saturating actuators

IEEE Control Systems, 1998
The objectives of this article are to concisely state the tracking control problem with actuator saturation, briefly review the current literature, and formulate the problem in a manual (flight) control context. The complexity of tracking control with saturation is demonstrated via a simple example.

Linear Systems with Non-Actuator Saturation

2001
Throughout the previous chapters, we have closely examined linear systems with saturating actuators in a systematic manner. We will conclude this book with some results on linear systems subject to non-actuator saturation. We will establish necessary and sufficient conditions under which a planar linear system under state saturation is globally ...

Linear System Control via Dynamic Saturating Actuators

IFAC Proceedings Volumes, 2010
Abstract The problem of controlling systems via saturating actuators is addressed. In most previous studies the actuator is represented by a simple saturation. However, there are practical situations where such simple model is insufficient. Then, the actuator dynamics must be accounted for.

Actuator saturation compensation for self-tuning controllers

International Journal of Control, 1994
In linear control system design, it is often assumed that control is unbounded. However, due to practical constraints, actuator saturation often occurs. To compensate for the actuator saturation, heuristic techniques are developed and can be found in the literature. In this paper, the optimal compensation for a class of sub-optimal control laws such as

Synthesis Algorithm for Control System with Saturated Actuator

Differential Equations and Control Processes
The paper presents a generalized algorithm for designing closed optimal systems with a dynamic controller and a nonlinear actuator. The purpose of the proposed algorithm is to identify the area of system performance degradation, manifested as unintentional oscillations, due to the influence of actuator nonlinearity and reduce this area.

Engine idle speed control using actuator saturation

IEEE Transactions on Control Systems Technology, 2000
Presented in this paper is the design and experimental validation of a saturating engine idle speed controller for a Ford V-8 fuel injected engine. The nonmeasurable external torque disturbance perturbing engine speed is delivered from the power steering pump.
