With increasing concerns on environmental issues, vast renewable energy is integrated into power systems worldwide, especially wind power. However, its essential uncertainty introduces great challenges into power system operation. Additionally, the emission-constrained generation dispatch problem need to be further studied in the background of restructured power systems, as just the total emission...
Fault diagnosis is of significant importance to the robustness of aeroengine control systems. This paper makes use of full-order unknown input observers (UIOs) to facilitate the diagnosis of sensor/actuator faults in engine control systems. The built-in “ui-observer” function in Scilab, however, can not give satisfying performance, in terms of observer realization. Hence we rewrite this UIO program...
In this paper, we focus on the problem of the fault-tolerant control (FTC) of aircraft in the presence of both unknown input disturbance and sensor failure. In the proposed method, the sensor faults will be detected by a full-order unknown input observer (UIO), and then the faults will be isolated by a bank of UIOs in the framework of the generalized observer scheme. Finally, the faulty sensor measurement...
Due to their ability to model sequential data without making unnecessary independence assumptions, conditional random fields (CRFs) have become an increasingly popular discriminative model for human activity recognition. However, how to represent signal sensor data to achieve the best classification performance within a CRF model is not obvious. This paper presents a framework for extracting motif...
In terms of double-controller design technology and relay feedback identification method an autotuning IMC structure with two degree of freedom (TDF-IMC) is proposed in this paper. The model parameters of the controlled process are identified via a modified relay feedback identification method. The setpoint tracking IMC controller and disturbance attenuation IMC controller are designed, respectively,...
A simple controller design method for a two-degree-of-freedom (TDF) Smith predictor control system is investigated to obtain an improved performance of setpoint tracking and disturbance attenuation. The setpoint tracking controller and disturbance rejection controller in TDF Smith scheme are designed as ideal PID controller and approximate derivative PID controller, respectively. Each controller is...
