Control Strategy

Strengths

Limitations

References

Deadbeat Controller

High precision, robustness, and fast response

High dependence on system model; large tracking errors under suboptimal conditions

19,20

Hysteresis Controller

Simple implementation and fast dynamic response

Variable switching frequency leading to increased switching losses

21,22

Sliding Mode Control (SMC)

High robustness against disturbances and uncertainties

Potential stability issues and chattering effect

23,24,25,26

Fuzzy Logic Control (FLC)

Handles vague/imprecise inputs; does not require an exact model

Strongly relies on expert knowledge; requires frequent rule base updates

25,26

Repetitive Control

Effective for periodic disturbances

Poor dynamic response; limited performance in fast-changing conditions

27,28

Lyapunov-based Controller

High tracking accuracy

Variable switching frequency; high computational burden
