Which of the following applications work with a bidirectional bus system?

Pulse width modulation (PWM) is a method of approximating continuous time signals by using pulses that are either completely on or completely off and it can be used as an alternate way to represent the process input signal produced by a PID-Controller. To use the PWM signal sense full the system has to respond ______(1) and the PWM version has to be ______(2).

If you are tuning a PID Controller with the Ziegler-Nichols

method, without measuring or using a lookup table, which

parameters must be increased and which parameters must

be set to zero?

The picture shows a typically three layers model of the

organizational structure, which is common in the industry.

Which of the listed elements you can use for the Operating Level?

At the closed position the spring force is 𝐹1 = 40 N. The spring rate is 𝑘 =

10 N/mm. During normal operation the plunger is compressed 6 mm from the

closed position. 

What is the spring force at the normal operating position?
