Abstract: We give here a brief survey on the recent development of modern control theory. In particular we give a review of the results recently obtained in both theory and applications by authors of our country in the following directions: theory of linear control systems, theory and applications of optimal control, control systems containing typical nonlinearities, digital control systems with quantized inputs and quantized outputs, stochastic control, control and identification of systems with distributed parameters, differential games, system identification, adaptive control and so on. The author expresses his personal opinion and from the needs of engineering practice as well as from theoretical development he 15roposed several problems that may be of interest for further research in the different directions mentioned above.
