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...

this paper focuses on the effects of closed- control on the calculation of the dynamic load carrying capacity (dlcc) for mobile-base flexible-link manipulators. in previously proposed methods in the literature of dlcc calculation in flexible robots, an open-loop control scheme is assumed, whereas in reality, robot control is achieved via closed loop approaches which could render the calculated ...

This is an overview of distributed computer control systems from the perspective of control performance and the requirements of a safety-critical application. The common timing issues, here called the timing problems, are stated from a control point of view: control period, control delay, jitter and transient error. seen as disturbances acting on the closed loop via the digital computer system,...

The specification of load current transient response at the output of a power supply is subject to requirements related not only to the load transient demand itself – specifically load current step magnitude and slew rate – but also to the characteristics of the power supply. In general, the voltage regulator control loop design constitutes an important element and when fast transient response ...

this article presents a fuzzy robust mixed - sensitivity gain - scheduled h controller based on the loop -shaping methodology for a class of mimo uncertain nonlinear time - varying systems. in order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by takagi and sugeno’s (t - s) fuzzy approach. both loop - shaping methodology and...

Damping injection is a well-studied tool in nonlinear control theory to stabilize and shape the transient of mechanical systems. Interestingly, coupled damping yielding gyroscopic forces has received far less attention. This paper aims fill this gap for that couple actuated unactuated coordinates. First, we establish sufficient conditions stability closed loop. Then, provide analytic results pr...

This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a  vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...

A new open-loop heat flux control technique has been developed to conduct transient thermal testing of thick, thermallyconductive aerospace structures. This technique uses calibration of the radiant heater system power level as a function of heat flux, predicted aerodynamic heat flux, and the properties of an instrumented test article. An iterative process was used to generate open-loop heater ...

This letter presents a design-oriented analysis on the transient stability of grid-forming (GFM) converters using single-loop voltage-magnitude control scheme. It is revealed that used controller has critical impact stability. differs from GFM vector-voltage control, whose dominated by outer power loops. The theoretical findings are verified experimental tests.
