| Description |
Creation of a robust control system for work in all range of change of radiuses of unwinding of a circle with a tape is considered. In the previous works synthesis of optimum regulators, observers and jacks for three radiuses of unwinding of a circle with a tape – initial, average and final is carried out. It is natural that these regulators, observers and jacks have various factors of strengthening for different radiuses of unwinding. The purpose of article is synthesis and research of response characteristics of digital robust control system of dual-channel control by winding machine on channels of regulation of rotational speed of the drive mechanism and a tension of a winding tape. Mathematical model of the winding machine as object of robust control system on channels of regulation of a tension of a winding tape and rotational speed of the drive mechanism taking into account the executive engines of drive and brake mechanisms it was constructed in the previous operations. The spinner consists of the drive mechanism, the charge coil with a tape and a section of a winding tape. External forces are: force of the drive mechanism and force of the brake mechanism. The executive engine of the drive mechanism is located at the considerable distance from the winding machine and brings into rotation spinners through the general reducer. For high-speed winding machines, especially for dynamics of movement of the winding machine is influenced by existence of elastic elements both between the drive engine and a reducer, and between a reducer and the drive mechanism. Thus rotational speeds of the drive Vд engine, a reducer of Vр and the drive Vп mechanism, especially in transient phenomena, do not match. Machine transmission as three-mass system with three concentrated masses is considered: in mass - the mд engine, mass of a reducer of mр and an inertia moment of the drive in mechanism, connected by elastic shaft with stiffness coefficients С1 and С2 and coefficients of internal viscous friction of β1 and β2. Then we will receive the following system of equations. The state vector () Xt G .The matrix of a status of the winding machine as three-mass system is entered. Now the widest circulation received the solution of the task of digital robust control in a time domain. The solution of the task in a time domain is considered in case of the system description by means of the Δoperator. As an example in figures transient phenomena of rotational speed of the drive engine, force of elasticity, rotational speed of a reducer and force of the brake mechanism according to the job for a regulator of rotational speed of the drive mechanism in robust control three-mass discrete system are shown. Apparently from these figures, in system there is an astatizm on channels of regulation of speed of the drive mechanism and a tension of a winding tape, both on setting, and on perturbing influence. Influence of cross setting influences is shown only in transient regimes, and output coordinates are equal in the set modes to setting influences. Transient phenomena are strongly oscillatory that is caused by existence of elastic elements in transmission of the drive mechanism.
