Stability and quality of control in feedback control systems under failure were analyzed, and design methods of the controller were developed, which preserve stability and quality of control under such circumstances as a break down in some of signal lines or parameter variations in plants. The main results are as follows:1. A necessary and sufficient condition for integrity was derived in terms of the return difference matrix of a closed loop in normal operation. A series of design methods to realize integrity were developed.2. A design method of a controller was developed, which preserves quality of control as well as integrity under failure in feedback loop.3. A new concept of responsible control was proposed. It is a control scheme where each control agent is responsible in respective set of outputs. By this responsible control scheme, one can expect strong integrity.4. A general stability condition for a system with time-delay was derived.5. A general theory of an optimal regulator for a system with time-delay was developed.6. A design tool for a controller possessing integrity was implemented in an in-house CAD system - ISSACS.

分析了反馈控制系统在故障情况下的稳定性和控制品质，提出了控制器的设计方法，在某些信号线故障或被控对象参数变化的情况下保持了控制的稳定性和控制品质。主要结果如下：1.利用闭环系统正常运行时的返回差阵，给出了闭环系统完整性的充要条件。提出了一系列实现完整性的设计方法。提出了一种控制器的设计方法，在反馈回路失效的情况下，既能保证控制质量，又能保证系统的完整性。提出了责任控制的新概念。这是一种控制方案，其中每个控制代理负责各自的输出集合。通过这种负责任的控制方案，可以预期具有很强的完整性。给出了时滞系统的一般稳定性条件。建立了时滞系统最优调节器的一般理论。在一个内部CAD系统ISSACS中实现了一个具有完整性的控制器设计工具。
