摘要:
We usually describle a comparatively more complex control system,especially a multi-inputs and multi-outputs system by time domation analytical *** the system's controllability means whether the system is controllable according to certain *** involves not only the system's outputs' controllability but also the controllability of the system's partial or total *** movement is described by difference equation in the linear discrete-time ***,the problem of controllability of the linear discrete-time system has been converted into a problem of the controllability of discrete-time difference *** thesis makes out the determination method of the discrete-time system's controllability and puts forward the sufficient and necessary conditions to determine it's controllability by making a study on the controllability of the linear discrete-time equation.
