To the optical mechanical complexes of tracking and positioning, strict requirements are produced on the dynamics and permissible errors under such conditions as external and internal nonstationary disturbances, as well as presence of elastic deformations in the links of the driven mechanism. In modern systems, adaptive control algorithms have proven themselves as complementary to the main control...
This paper describes fuzzy cooperative coevolution adaptive control which uses a common genetic algorithm to obtain the coefficients of the adaptive fuzzy regulator. The plant under consideration is multi-mass drive system with elastic couplings. A comparison between systems with fuzzy control and conventional PID-control is considered. It is shown that fuzzy method allows to suppress torsional vibrations...
Torque pulsation in permanent magnet synchronous motor impairs their performance in critical applications, particularly for direct-drive. A practical approach to compensation of selected torque harmonics is presented. The approach consists of two steps: identification of dominant torque harmonics (the cogging harmonics and the flux linkage harmonics) and cuckoo search algorithm to tune the compensation...
Modern electromechanical systems due to the respective electric drives control algorithms, have to ensure maximum achievable requirements for precision and control dynamics of the spatial coordinates of the bodies that make up their structure. The features of these systems are changing the dynamic parameters, which include, changing the moment of inertia of bodies relative to the axis of rotation,...
The article discusses the features of the control system of telescope axes' drive. Conventional PID control system can not reach a satisfaction tracking accuracy in the case of low speeds of axes movement due to elastic coupling and friction action in these two-mass systems. As a consequence in the systems oscillations occur. In this study, fuzzy adaptive PID controller is described and this controller...
This paper presents an algorithm of fuzzy adaptive PID controller and addresses its application in vibration suppression of a two mass rotating system. In a performance comparison between the proposed controller strategy and a classical PID control scheme extensive simulations confirmed the superiority of the proposed fuzzy adaptive controller. The results show that accurate tracking performance of...
