Embedded Model Control (EMC) methodology is applied to web-winding control problems. These require time-varying Embedded Model and adaptive control law, because of a variable winder radius; disturbance estimation and rejection, because of friction and variable web speed and acceleration; sensorless reel radius estimation; and robust stability and performance in the presence of web and gear vibr...

The disturbance accommodating control theory provides a method for designing feedback controllers which automatically detect and minimize the effect of waveform-structured disturbances. This paper presents a disturbance accommodating controller which utilizes a Kalman estimator to determine the necessary corrections to the nominal control input and thus minimizes the adverse effects of model un...

A bstmct— This paper proposes a new Hm yawmoment control scheme using brake torque for improving vehicle performance and stability especially in high speed driving. Its characteristics is that only one brake is used for control depending on the vehicle state. Steering angles are modeled as a disturbance input to the system and the controller minimizes the difference between the performance of t...

In this paper, a nonlinear robust control approach is applied to design a controller for the Static Synchronous Compensator (STATCOM). A robust control dynamic model of STATCOM in a one-machine, infinite-bus system is established with consideration of the torque disturbance acting on the rotating shaft of the generator set and the disturbance to the output voltage of STATCOM. A novel recursive ...

The state-dependent nonlinear external disturbance compensation problem is considered. No prior information about the disturbance is assumed except the periodicity of the disturbance with respect to a state variable, which is termed a ‘state-dependent periodic disturbance.’ The key idea of the proposed new adaptive compensation method is to make use of this known state-dependent periodicity. In...

In this paper, a multi-objective optimization model is presented to estimate the practical stability region and maximum endurable disturbance ejection for a small-signal power system dynamic model with saturation nonlinearities and disturbance rejection. Iterative algorithms are developed o solve for Pareto optimized solutions (POS) of this optimization. Furthermore, as an application of this a...

The incorporation of renewable energy sources for the sustainable electricity production is undertaking a more prominent role in electric power systems. Thus, it will be an indispensable incident that the characteristics of future power networks, their prospective stability for instance, get influenced by the imposed features of sustainable energy sources. One of the distinctive attributes of t...
