In this paper, the acceleration of a car under performance tests is estimated by using a Kalman filter. Here, the observation vector consists of the observation of both the velocity and the longitudinal acceleration of the car. This is the process vector and is the input of the filter. The output is the filtered estimate of the state vector, which consist of the velocity and longitudinal acceleration...
In this paper, the performance of a sensor system based on a piezoresistive accelerometer for automotive applications was improved by using a block least-mean-square (BLMS) adaptive filter. The accelerometer was tested for a multi-frequency acceleration excitation and the results of the experiment showed that for this type of excitation, which is typical of real-life problems in today's cars, the...
In this paper, robust control techniques are used to design a buck-boost dc-dc power converter. The robust control techniques used in this paper are based on frequency-domain controller design ideas, and the stability margins of the two controllers designed in this paper allow us to guarantee that both controllers provide robust stability. That is to say, the transfer function of the power converter...
In this paper, the uncertainty of measurement of a robust photometer circuit (RPC) was estimated. Here, the RPC was considered as a measurement system, having input quantities that were inexactly known, and output quantities that consequently were also inexactly known. The input quantities represented information obtained from specifications of manufacturers, calibration certificates and tabulated...
