Analysis of Sliding Mode Equations of Electric Drive Control System with Acceleration Observer
Year: 2026
Type: conference-paper
Abstract: Relay-based control systems are most effective in controlling electric drives that have high speed and operate under various disturbances. High-precision electromechanical systems require acceleration feedback calculated using derivative observers. The specific properties of sliding modes that generate ripple in the state variables are naturally taken into account by observers, which are designed as relay systems. The coexistence of several self-oscillating modes makes analytical assessment of transient processes essential, since many practical mechanisms do not tolerate overshoot. By jointly analyzing the sliding mode equations of the electric drive and the observer, this paper substantiates the aperiodic nature of transient responses in systems synthesized using the N-i switching method. An assessment of the system's sensitivity to parameter variations is given, and transient processes are also presented for a representative numerical example.
