Abstract

Optimized and controlled electromechanical systems should ensure best achievable performance and capabilities, such as functionality, stability, robustness, and disturbance rejection. Consistent control laws should be designed and implemented as analog or digital controllers. One designs closed-loop systems to optimize dynamics and guarantee stability. Optimal control laws should be consistent with device physics and hardware. One applies stability criteria, assigns performance goals, and solves the optimization problems by minimizing performance functionals. We document various design methods. Some methods result in control laws that assume that all state variables are measurable or observable. Many variables cannot be measured. The minimal-complexity control laws are synthesized to: (1) Guarantee near-optimal performance; (2) Minimize system complexity; (3,4,5) Ensure hardware consistency and simplicity.
