A method using laser infrared radar to measure information of the Limber in motorcade is designed and presented. LMS291 is equipped in front of the vibrator to collect information of the Limber. Radar information is processed in TMS320LF2407A DSP to get distance and angle. Relevant control information is produced in ATmega16A, distance and angle message and simple relevant control information are...
For a nonlinear system, the state feedback in the feedback linearization is reconstructed on the equilibrium manifold which is parameterized by a scheduling variable. So that, compared with the former state feedback, the corrected state feedback is independent on the unmeasurable states, which could greatly decrease cost of the whole control system and is easier to realize, because it does not require...
For the complexity and difficulty problem of states feedback and measure based on exact feedback linearization method, a simplified state feedback design method without requirement of states measure is put forward. First, the nonlinear model is introduced, and is linearized through exact feedback linearization method with a state feedback law and a state transform. Second, according to the linear...
A modified LPV (Linear Parameter Varying) modeling technique for nonlinear system was put forward and is applied in a turbofan engine model and control analysis. First, a quasi-LPV model of a turbofan engine is designed at various engine operating points using linearized models and the scheduling variable is the fan speed. Then, according to the feedback method, the quasi-LPV model is modified by...
A modified LPV (Linear Parameter Varying) modeling method for nonlinear system was put forward and is applied in modeling a turbofan engine system. First, a quasi-LPV model of a turbofan engine is designed at various engine operating points using linearized models of the engine dynamics and the scheduling variable is the low-pressure compressor speed. Then, according to the feedback method, the quasi-LPV...
In this paper, a multi-sensor data fusion algorithm was put forward. First, based on the statistics, the standard deviation relating to the fusion value of sensors' measured data was used to estimate sensor's variance. Secondly, by using this estimate variance, a new adaptive weighted fusion algorithm for multi-sensor data fusion, as well as its iterative form, was put forward. Then, a “memory attenuation...
