In this paper, the speed tracking problem of interior permanent magnet synchronous motor (IPMSM) an electric vehicle is studied. A cascade control strategy based on active disturbance rejection (ADRC) and a current improved duty cycle finite set model predictive (FCSMPC) are proposed, both which can reduce torque ripple as well computational burden. First all, in linearization process, some non...

In order to obtain the best power in wind energy conversion system (WECS) of direct-driven surface-mounted permanent magnet synchronous generator (SPMSG), active disturbance rejection control (ADRC) is introduced track motor speed real time. The algorithm provides a new design concept and an inherent robust controller component that requires very little information. Aiming at problem parameter ...

Aiming at the problems of difficult attitude stabilization, low landing accuracy, large external disturbance and slow dynamic response during quadrotor on wave glider, an improved series active rejection control method for is proposed. The controller with inner-loop angular velocity outer-loop position based (ADRC) designed by analyzing model quadrotor. A tracking differentiator (TD) adopted to...

The flying around monitoring task of space tumbling target is one the key links its on-orbit service. Considering practical constraints system inertia uncertainty, external disturbance, actuator saturation, and fault in engineering practice, a robust composite controller based on radial basis function (RBF) neural network proposed. First, new line sight rotation (RLOS) coordinate system, relati...

This paper presents a robust model independent control method for the stabilization of a four-rotor rotorcraft, which is popularly known as the quadrotor helicopter. In addition, a detailed dynamic model is presented for the formulation of the proposed control law and a prototype platform heavily utilizing printed circuit board technology is proposed for experimentation. This paper focuses on c...

This paper presents a novel extended state observer (ESO) approach for class of plants with nonlinear dynamics. The proposed estimates both the variables and total disturbance, which includes exogenous endogenous disturbance. study’s changes can be summarized by developing sliding mode higher-order augmented function estimation error correction terms (SMHOESO). By including multiple enhanced st...

As the important signal of once-through boiler's water-fuel ratio control, intermediate point temperature of supercritical boiler plays a key role in the decision of steam and water’s boundary, the match of fuel and water, the control of main steam temperature. The condition of its control directly impacts the once-through boiler’s safety and economy running. For an uncertainty model, a good co...
