One of the beneficial applications of an automotive control system is the active control of the suspension system. One feedback control system uses a shock absorber consisting of a cylinder filled with a compressible fluid that provides both spring and damping forces. The cylinder has a plunger activated by a gear motor, a displacement-measuring sensor, and a piston. Spring force is generated by piston displacement, which compresses the fluid. During piston displacement, the pressure imbalance across the piston is used to control damping. The plunger varies the internal volume of the cylinder. This system is shown in Fig.la. The system can be represented by the block diagram shown in Fig. 1b, where: Control output Plunger Gear motor Cylinder Controller Piston Liquid Sensor output Damping orifice Piston travel Piston rod Fig.1a: Shock absorber

QUESTION 1 A vertical vibrating system of 5 kg of mass and 500 N/m of spring stiffness is critically damped. The system is excited by a step input force f(t) = 50 N to generate an output vertical motion y(t), in metres, and t-is the time in seconds. 1.1. Determine the transfer function of the system 1.2. Provide an equivalent block diagram with a unitary negative feedback to control the motion y(t) 1.3. Using s-plane, locate the closed loop pole(s) and zero (s) of the system and provide the reasons of stability or non-stability of the system 1.4. Using the technique of partial fractions, establish the analytical expression of the time response of the vibrating system.
An engineer is designing a transfer line. The line has 15 stations. Stations 1 through 10 should have the same reliability. Each station is expected to operate approximately 1000 cycles between failures. The last 5 stations are expected to break down about once every 600 cycles. Repair times will vary but should average about the equivalent of 12 cycles in duration. a. Find the availability of the line. b. Suppose you could add one buffer of size 20. Where would you place this buffer? Find the increase in availability
In a negative feedback system ,the error can be calculated by subtracting the feedback value with input value. Select one: True False

Below is a very common feedback block system. It is a 1dof, and unity-feedback system. The input is the reference command R(s). This is what flows out of thin air, into the system. All other signals in the system (e.g. U, Y, etc.) will depend on R(s). R(s) a. E(s) e. K U(s) G Y(s) Write the algebraic relation between the output Y(s) and the reference R(s) in terms of G and K?.
