Non-fragile robust control problem of a fan system is studied. It is pointed out that this problem of the fan system is really a non-fragile robust performance problem, the problem of the fan control system with both non-fragile robust stability and performance requirements(bandwidth and other performances). It is also suggested that the design of the non-fragile robust performance of the fan system...
The paper addresses the problems about calibration of vector modulation error such as EVM: first, lacks traceability. Second, lack of error setting. To solve the problems, we proposed “CW combination method” three years ago, which is using combination of CW to calibrate vector signal analyzers in the aspect of MPSK modulation. This paper presents the technical improvement of “CW combination method”...
This paper presents the design of the μ robust performance of a hydro Turbine speed governor. It can be used to solve the μ robustness problems, which can't be done by the conventional H∞ robust performance designs. High frequency oscillation and large amplitude of output and control variable of the control system are exhibited by a conventional H∞ robust performance design method. It is pointed out...
Non-fragile robust control problem of an air fuel ratio is studied. Under the premise of guarantee certain performances (overshoot and the settling time of the system, etc.), it is proposed that the μ-synthesis non-fragile robust performance design for the control system of the air fuel ratio is essentially to tolerate the greatest uncertainty. It is pointed out that this problem is really a non-fragile...
Non-fragile robust control problem of a paper basis weight is studied. It is pointed out that this problem is really a non-fragile robust performance problem, the problem with both non-fragile robust stability and performance requirements(bandwidth and disturbance attenuation). It is also suggested that the design of the non-fragile robust performance can be formulated as a μ-synthesis problem, if...
The plant of test turntable system contains model uncertainties as time-delay, parameters, etc. The realizations of controllers can't be quite accuracy. The design concepts of the non-fragile robust performance of the system with the perturbations of the controlled members and the controllers are presented. It can be used to solve the non-fragile robustness problems of the turntable control system...
The non-fragile robust control design is discussed for the controlled plant and the controller with unknown uncertainty and different from other robust control methods were given, that is, the system can tolerate the greatest uncertainty on the basis of the guaranteed certain performance. Based on the meeting certain bandwidth and overshoot, a non-fragile robust performance design method is presented,...
