Pole Placement Based ZN (Zhang Neurodynamics) Control in Continuous and Discrete Forms for TILS (Time-Invariant Linear System) Output Tracking
摘要
The output tracking problem is an important topic in the field of system control, and the pole placement based Zhang neurodynamics (PP-based ZN) method is an effective way to solve this problem. In this paper, for the convenience of digital hardware implementation, two time-discretization methods, namely, Euler discretization and time-invariant linear system (TILS) special discretization, are applied to conduct discrete control and its simulations based on the PP-based ZN output tracking controller. In numerical experiments, both discrete forms show high precision for different sampling interval gaps and desired tracking trajectories (i.e., paths). Besides, through the discussion of simulation results, the similarities and differences between the two discrete forms are compared.
