Chapter 4

• 1st Order Rise Time (4.9, 159)
• 1st Order Settling Time (4.10, p. 159)
• 2nd Order Peak Time (4.34, p. 171)

Other

• Geq from T for unity feedback

\(\begin{align} G_{eq}&=\frac{T}{1-T}\\ T&=\frac{N_T}{D_T}\\ G_{eq}&=\frac{N_T}{D_T-N_T} \end{align}\)

• T from Geq for unity feedback

\(\begin{align} T&=\frac{G_{eq}}{1+G_{eq}}\\ G_{eq}&=\frac{N_G}{D_G}\\ T&=\frac{N_G}{D_G+N_G} \end{align}\)

Denied / Not Needed

• Motor transfer function constants (2.162 & 2.163, p. 79) - will not need
• Transfer function from state space (3.73, p. 133) - will not need
• General 2nd order transfer function (4.22, p. 166) - need to memorize
• Mason's Rule (5.28, p. 240) - need to memorize that and what the terms mean.
• Formula for system type, static error constants, and steady state errors (Table 7.2, p. 336) - need to memorize
