Synthesizing discrete PID-controllers of the motion partition method. (English. Russian original) Zbl 0790.93022

J. Autom. Inf. Sci. 25, No. 4, 63-67 (1992); translation from Avtomatika 1992, No. 4, 68-73 (1992).
Summary: Controllers with a modified PID-law are suggested for the objects with incorrectly preset or time-varying parameters. The essence of modification lies in the introduction of small parameters into the system. It causes the initiation of fast and slow motions in the system. It is equivalent to the control by the higher derivative. Formulas of controllers in explicit form are obtained. Computation procedure of the controller parameters is explained in detail.
