The invention belongs to the technical field of software engineering, in particular to a software quality run-time optimizing method based on control theory and goal inference. The invention introduces a value viewpoint in the software engineering based on value, defines a value measurement model specific to a goal system as a system total quality feedback from a client business point of view and achieves the software quality run-time optimization based on demand goal inference on the basis of the system total quality feedback. The invention uses a PID controller to dynamically regulate priority levels (quality preference) of relevant run-time quality attributes and takes the priority levels as input to conduct the demand goal inference of preference drive. A demand goal configuration project obtained by the goal inference is used for guiding dynamic reconfiguration of a run-time system structure, thereby achieving the optimal regulation of the system. The real time feedback-based software system run-time tot
