This work is devoted to the creation of effective optical logic systems based on the use of light emitter of a certain color directly as a fuzzy variable — the carrier of logical information and the basis for building logical solutions by transforming light emitter with appropriate light filters. Optical processing of color information, which reflects different values of input data (considered on the example of expert evaluations), is carried out by the proposed structural construction of fuzzy logic gates (logic coloroid) and is significantly simplified, in relation to existing systems, due to the implementation on the properties of additive and subtractive color processing using fairly simple light filters. A fuzzy database was formed based on the definition of the quantum of information as the corresponding color, and the components of the optical logic system based on the additive and subtractive processing of the light emitter of the corresponding colors; the basics of the synthesis of logical inference and decision-making systems have been developed. The paper synthesizes a generalized structural diagram of an optical logic coloroid as a basis for creating a multi-level decision-making system for further application in artificial intelligence systems. Schemes of optical logic coloroids can be combined into series-parallel hierarchically organized schemes, the color of the used light filters can also, in addition to expert assessments, reflect the tactile information of sensor systems about the environment, which is necessary for the formation of appropriate logical assessments or decisions. The use of color as a carrier of logical information allows you to create fast-acting technical devices with performance based on the calculations of which the speed of light is used to form a certain array of logical solutions.

The article considers optimal systems that provide dynamic systems with highcontrol quality indicators: speed, accuracy, and low energy consumption. An approach to the synthesis of robust-optimal systems based on the use of feedbackwith a variable structure is being developed and includes the following mainstages: planning of the programmed optimal trajectory; determination of moments of switching of control functions in feedback loops of the object; synthesis of control functions in the corresponding feedback loops of a multidimensional object. The application of the proposed order of synthesis of systems witha variable structure for various types of objects based on the preliminary construction of optimal programmed trajectories of stabilization of dynamic processes allows optimizing the stabilization processes of nonlinear non-stationarysystems of high order. Optimal programmed stabilization trajectories are formedfrom segments established relative to the corresponding derivative of the motioncoordinate, based on polynomial forms for given boundary conditions and theoptimality criterion, taking into account limited control values, and are solvedfor the time of moments of switching of control and the time of the end of thetransition process based on a system of algebraic equations. Control synthesis iscarried out taking into account the initial values based on the equations of thebalance of forces and moments efforts on the moving object and their derivatives. The optimal trajectory and control are formed in such a way that, duringthe synthesis of an additional robust control circuit (with feedback from theoutput of the object) to compensate for the incomplete certainty of the mathematical model and uncontrolled (unmeasured) disturbances and noises, sufficiently limited areas of changing the coordinates of the moving object relative to given values. In the future, this allows the construction of sufficientlyeffective and practical in the implementation of robust-optimal control systems, for example, marine mobile objects, quadcopters, that function in conditions of considerable uncertainty.
