This thesis is concerned with stability analysis and controller design of interval positive systems with delay. The research scope is discrete-time systems. The interval and delay time contained in the system are the factors of uncertainty. For the problems of positiveness and stability analysis, we derive some new sufficient and necessary conditions. Based on these conditions, the design of the controllers with the state feedback can be applied to the stabilization design of the control system. Using the results of the foregoing analysis, the parameters of the controllers are sought in conjunction with the linear programming method. Finally, taking the actual discrete-time interval positive system with delay as an example. The simulation results,show that the designed controllers are effective and applicable.
