Top Phase Crossover Frequency MCQ Objective Questions
Phase Crossover Frequency Question 1:
In above bode plot, the gain cross one frequency & phase cross our frequency respectively are
Answer (Detailed Solution Below)
20, 7.5
Phase Crossover Frequency Question 1 Detailed Solution
at Gain crossover frequency
log \(\left| {G\left( {J\omega } \right)} \right| = 1\) (which is at ω = 20)
at phase crossover frequency
\(\angle G\left( {J\omega } \right) = - 180^\circ\) which is at ω = 7.5
Phase Crossover Frequency Question 2:
Phase crossover frequency of the system \({\text{G}}\left( {\text{S}} \right) = \frac{{\text{K}}}{{{\text{S}}\left( {{\text{S}} + 10} \right)\left( {{\text{S}} + 20} \right)}}\) is(in radians)
Answer (Detailed Solution Below) 14 - 15
Phase Crossover Frequency Question 2 Detailed Solution
\(G\left( S \right) = \frac{{\left( {\frac{K}{{200}}} \right)}}{{S\left( {1 + \frac{S}{{10}}} \right)\left( {1 + \frac{S}{{20}}} \right)}}\)
Comparing with standard equation of Type 1, Order 3
\(\eqalign{ & \frac{K}{{S\left( {1 + S{T_1}} \right)\left( {1 + S{T_2}} \right)}} \cr & {T_1} = \frac{1}{{10}};{T_2} = \frac{1}{{20}} \cr & {\omega _{pc}} = \frac{1}{{\sqrt {{T_1}{T_2}} }} = \sqrt {10 \times 20} = \sqrt {200} = 14.142 \cr}\)
