This paper presents a method for the controller design of linear systems in the presence of actuator saturation and ***,a simple condition is presented,under which any trajectories starting from an ellipsoidΩ will be attracted to zero for linear systems subject to actuator ***,under this condition,when actuator saturation and actuator faults happen at the same time,the trajectories will remain inside an outer ellipsoidΩ,respectively for different mode *** stability and fault-tolerant ability of the system is measured by the size of these *** on the above mentioned condition,the problem of estimating the largest constraints is shown to be a optimization problem which can easily be adapted for controller *** example is given to illustrate the efficiency of the design method.

＜正＞ The 3D negative sequence currents arising from unbalance system operations in large turbogenerators are studied by using the finite element method. The mathematical models of the three dimensional negative sequence eddy current fields of large turbogenerators considering the flexible slots are firstly proposed. To emulate the distributed exciting sources of the negative sequence current fields with enough precisions, the geometrical complication of the stator are accurately modeled in the proposed solid models, making it be readily to take into account of practical distributions of the negative sequence exciting currents. And finally, the negative sequence eddy current fields of a 1055 MVA turbogenerator are studied extensively by using numerical simulation results.
