This lab sheet is designed to guide students through the experimentation they will need to conduct in order to complete the continual assessment element of their NG3H235 studies.The lab has been designed to cover a number of elements of control system design and synthesis, which are addressed in lectures. The objectives are:
1. to investigate the control of water level in a lab scale non-linear water tank which is fed by a centrifugal pump and discharges to a sump tank through a valve,
2. to understand the dynamics of the water tank by modelling it from first principles and by applying step tests to identify the system model at various operating points,
3. to design a proportional + integral controller for a specific operating point, implement it in software (as an analogue s-domain system, i.e. very fast sampling).
4. To allow scope for further investigations.
Find the tension in the thread: A thread is wound round a heavy homogeneous cylinder of mass m and radius. The cylinder is permitted to fall from rest and unwinds the thread.
Normally galvanized pipes are not used for steam. Mild steel with screwed or welded fittings are the norm. Pressure and temperature are very significant factors to be considered in
1. A hydraulic pump generates 240W and supplies hydraulic fluid at a rate of 5.1l/min to a linear actuator which has a bore size of 50 mm and a double piston rod diameter of 20mm.
A modified NRZ code known as enhanced-NRZ (E-NRZ) operates on 7-bit words; inverting bits 2,3,6 and 7; and adding one parity bit to each word. The parity bit is chosen to make the

Adhesives Adhesives are a substance able of holding materials together. A joint is formed among two solids is called adherends with a thin layer of adhesive among them. Mainly
STEP S FOR SOLVING PROBLEM FOR FINDING POWER: 1. Use formula stress (s) = force (Maximum Tension)/Area Where; Area = b.t that is, Tmax = σ.b.t 2. Unit mass (m) = r.b.t.
