Would it be possible to set a PID controller up on a PLC, and adjust it’s setpoint / AUTO / MANUAL selection from a SCADA system?

When trying to implement PID control, it is said that we typically find three types of processes, namely:

a) Resistance Type Processes

b) Capacitance Type Processes,

c) Inertia Type Processes. In most instances, Inertia processes are quite uncommon. Carefully consider your experience over the years, and describe an application, which according to your understanding of the subject matter, comprises of both Resistance and Capacitance effects.

A silicon sample is doped with 4.5 × 10¹⁷ cm^-3 boron atoms. Assume T= 300 K, n_i = 1.5 x 10¹⁰ cm^-3

^{What is the hole concentration and electron concentration?}

Draw an equivalent circuit and list the sequence of steps to connect jumper cables properly between two car batteries when trying to jump-start a car with a run-down battery. Be sure to label both the positive and negative terminals on each battery and the red and black cables of the jumper. I t is recommended that the last connection you make should be between the black jumper cable and the run-down car; and instead of connecting it to the negative terminal of the battery, you should connect it to the frame of the car at a point away from the battery. What is the rationale for this advice? Does it matter in what order the connections are removed when you have started the car?

1. How does a temperature sensor based on a diode work? Please provide a qualitative description and Include a circuit.

The controlled full wave rectifier is connected to the grid. The rms grid voltage is 230 Volt at 50 Hz. 24 Volt battery will be charged with 15A. An inductor, which is series connected to the battery, is used to limit the current ripple. Only The second harmonics of the output voltage is taken into account. The inductor R/L ratio is 50. The current ripple is allowed to be 4 amp peak to peak. Determine the firing angle and R for the circuit, for this design. Write the mat equations and Show the solution with detail.

a) alfa=? ( in rad ) b) R=?
