The analysis of simulation results obtained using soft computing technologies has allowed one to establish the following fact
important for developing technologies for designing robust intelligent control systems. Designed (in the general form for
random conditions) robust fuzzy controllers for dynamic control objects based on the knowledge base optimizer (stage 1 of
the technology) with the use of soft computing can operate efficiently only for fixed (or weakly varying) descriptions of
the external environment. This is caused by possible loss of the robustness property under a sharp change of the functioning
conditions of control objects: the internal structure of control objects, control actions (reference signal), the presence
of a time delay in the measurement and control channels, under variation of conditions of functioning in the external environment,
and the introduction of other weakly formalized factors in the control strategy. In this paper, a description of the strategy
of designing robust structures of an intelligent control system based on the technologies of quantum and soft computing is
given. The developed strategy allows one to improve the robustness level of fuzzy controllers under the specified unpredicted
or weakly formalized factors for the sake of forming and using new types of processes of self-organization of the robust knowledge
base with the help of the methodology of quantum computing. Necessary facts from quantum computing theory, quantum algorithms,
and quantum information are presented. A particular solution of a given problem is obtained by introducing a generalization
of strategies in models of fuzzy inference on a finite set of fuzzy controllers designed in advance in the form of new
quantum fuzzy inference. The fundamental structure of quantum fuzzy inference and its software toolkit in the processes of designing the knowledge
base of robust fuzzy controllers in on-line, as well as a system for simulating robust structures of fuzzy controllers, are
described. The efficiency of applying quantum fuzzy inference is illustrated by a particular example of simulation of robust
control processes by an essentially nonlinear dynamic control object with randomly varying structure.
