Other Prospects for Developing Methods of Optimal Control Synthesis

In this chapter, we consider some constructive perturbation methods for solving various control problems which amplify the techniques described in previous chapters. These methods arise from new problems of precise and efficient control of complex engineering systems, such as manipulation robots, large-scale space structures, etc. Control of these systems requires taking account of numerous perturbations of various physical natures: external force fields, the influence of the environment, dynamics of electrical actuators, distributed elasticity of structural elements, interaction of different parts of the system, imperfections of joints, etc.
