It is required by the industrial production to make industrial chains work properly.Industrial machine consists of a large and complex system of sensors and actuators and other components.Because of the precision and complexity of the components,system components have the possibility of failure,which causing the machine to stop running and other problems.When an industrial system component fails,the factory cannot work normally and causes losses.If such a failure occurs to the aviation industry production and the flight of spacecraft,the aviation industry will be shut down or the spacecraft will be out of order,which would bring economic losses and safety risks to national aviation units,the pilots and the people on the ground.In this conventional feedback control,state feedback has excellent dynamic performance but is not readily observable.Some dynamic output feedback consuming many more system resources.To circumvent the lack of feedback control of the two mentioned above,this research selects a static output feedback control strategy in linear system.Ultimately improves the security of industrial systems and aerospace systems to provide security for the people and for the country to avoid huge economic losses.In Chapter 1,the development of reliable control and HH_?control theory,the types of output feedback and their advantages and disadvantages,and the significance of studying regional poles are discussed.The 2nd chapter is the basic knowledge of mathematics.The concept of regional pole assignment is explained,the component failure model and failure handling method are discussed,and the lemma and notation were finally explained.The 3rd chapter develops a robust controller method for static feedback on the output of a linear system by accounting for a single sensor failure.The result is confirmed by numerical simulations.In Chapter 4,the interference factors are analyzed for the given HH_?performance index,and a reliable HH_?controller method for sensor failure is developed.Taking the requirement of the poles in the disc area as an example,in Chapter 5,a reliable HH_?controller for linear system output feedback is designed and its numerical simulation results are verified.In this research,a new type of static output feedback reliable controller is designed,which not only meets the requirement of HH_?index given by the closed-loop system,but also has a circular area pole.It successfully reduced the impact of the external environment or human interference on the system,corrected the shortcomings of the existing feedback control,and reached the standard of high-performance indicators.
