In this paper, distributed parameter process systems behavior is studied in frequency domain. Based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. By using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

In order to tracking the desired discontinuous output trajectory, we explore P-type iterative learning control law with initial state learning for impulsive differential equations. The sufficient conditions of open-loop and closed-loop iterative learning schemes in the sense of L-norm are established. Finally, an example is given to illustrate our theoretical results. 2014 Elsevier B.V. All rig...

This paper presents a novel nonlinear Internal Model Controller architecture that achieves linear rejection of input disturbances from the control signal. For a large class of SISO nonlinear systems, appropriate open loop stability properties guarantee closed loop tracking and disturbance rejection of asymptotically constant signals. The convenient tuning and improved performance is illustrated...

In development of Homogeneous Charge Compression Ignition (HCCI) engines, simultaneous control of combustion phasing and power output has been a major challenge. In this study, a new strategy is developed to control the engine power output and combustion phasing at any desired operating condition. A single zone thermodynamic model coupled to a full kinetic mechanism of Primary Reference Fuels (...

Two most common tasks in controller design is regulation and signal tracking. Regulating controllers try to keep system stably in a fixed state. Balancing an inverted pendulum or keeping the speed a car at constant level are most obvious examples of regulation problems. All kinds of servomechanisms, such as autopilots and robotic arms, are the examples of signal tracking problems. An open-loop ...

This paper studies open-loop tracking and feedback stabilization for nonholonomic systems. Using the concept of approximate inversion, results for drift-free, left-invariant systems on speciic matrix Lie groups are presented .

In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
