A controller for a satellite attitude control with transfer function G = 1 s 2 has been designed with a unity feedback structure

S_A_V [24]

Answer:

type 2, k = 4

Explanation:

(a) The transfer function of the controller for a satellite attitude control is

$G = \frac{1}{s^2}$

The transfer function of unity feedback structure is

$D(s) = \frac{10(s+2)}{s+5}$

To determine system type for reference tracking, identify the number of poles at origin in the open-loop transfer function.

For unity feedback system, the open-bop transfer function

$G(s)D_c(s)=\frac{1}{s^2}\frac{10(s+2)}{s+5}$

$=\frac{10(s+2)}{s^2(s+5)}$

Determine the poles in G(s)4(s).

s = 0,0,-5

Type of he system is decided by the number of poles at origin in the open loop transfer function.

Since, there are two poles at origin, the type of the system will be 2.

Therefore, the system type is

Type 2

The maximum capacity of a 2-lane carriageway of a four lane dual carriageway is 2000 veh/hour. due to pipe laying operations the

Yuki888 [10]

Based on the maximum capacity as a result of the pipe-laying operations, and the maximum capacity without obstruction to the four-lane dual carriageway, the mean speed of traffic in the bottleneck is -2.73km.

<h3>What is the mean speed of traffic?</h3>

This can be found as:

= (Maximum restricted capacity - freeflowing rate) / (Kb - Ka)

= (1,100 - 1,500) / (209 - 62.5)

= -2.73 km/h

The rate that the queue outside the bottleneck grows is:

= Free flowing rate - (mean speed of traffic x ka)

= 1,500 - (-2.73 x 62.5)

= 1,670 veh/hour
