This paper considers the problem of iterative learning control design for linear systems with data quantization, where the system matrices contain uncertain parameters. It is assumed that the control input update signals are quantized before they are transmitted to the iterative learning controller. A logarithmic quantizer is used to decode the signal with a number of quantization levels. Then, a...
This paper shows that a comprehensive multivariable approach of autopilot design that mixes sliding mode and PID leads to robustly satisfactory results for underwater mobile robot. The 6-DOF linear equations of motion can be divided into three subsystems for speed control, steering, and diving. The sliding mode algorithm is designed for steering control and PID is used for diving and speed control...
A calibration problem for log sensor of UUV is established and the problem can be divided into two separate parts: misalignment angle and scale factor of log sensor. Instead of using the conventional least square algorithm, a fine calibration approach based on M-estimate is used to suppress the effect of non-white noise. The adaptive factor relation to calibration precision is brought forward which...
To aid the corrosion diagnosis of a grounding grid, test poles are suggested to implant on some nodes. A genetic algorithm based test poles allocation optimization approach is suggested to work out the set of schemes to make all of the branches clear with the least test poles. The N-X+Y principle is put forward, with which, the test pole allocation scheme to make as much as possible branches clear...
In order to make all of the branches of a grounding grid testable, test poles are suggested to implant on some nodes of the grounding grid. A hierarchical simplification model of grounding grids is proposed, based on which, the testability of the branches is evaluated by an iteration approach. A genetic algorithm based test poles allocation optimization approach is presented. The purpose is to make...
