An Electric Rail Transportation System The control of transportation systems is an interesting design and area. Many European trains are electric, so control of electric reaction motors is common in that area of the world. Desired speed inputs to the system are made by the operator, with an over-ride in case of emergency. In San-Francisco, the BART (Bay Area Rapid Transit) system is designed to automatically vary the speed as conditions warrant, without human intervention. Manned aircraft and space flight are further examples of transportation systems where control inputs to the vehicle are generated by an auto-pilot, The same methodology can be applied to bus, car and passenger train operation to improve performance. In this problem, we consider a velocity and position control system for a rail vehicle. Figure 1.1 fig 1.1 Vehicle model shows the relation between motor drive and velocity for an electric rail car. i. If a unit step function is given as input to this system, what should be the magnitude of steady state value of velocity produced in km/s. What will be the value of time constant 'T' for this system. What should be the velocity of this rail car at first time constant. ii. Now suppose, that the velocity of the car is to be controlled through a velocity controller in cascade with the vehicle model and a velocity sensor in feedback (negative feedback) with the same vehicle model G(s) as shown in figure 1.1. This system has input 𝑉𝐷(𝑠) and output as 𝑉(𝑠) and named that system as "Vehicle with velocity control feedback loop". Where 𝑉𝐷(𝑠) is the desired velocity of the vehicle and 𝑉(𝑠) is the current velocity of the vehicle. You have to design the closed loop form of this system and derive the relation for the transfer function 𝑇𝑣(𝑠) for this system. The gain of the velocity controller is and velocity sensor is . iii. What will be the type of this system. Determine the error transmittance of this system using the relation in terms of 𝑇𝑣(𝑠). Note: Remember, that the feedback gain is not unity this time. iv. Determine the steady state error for this system against step input as well as ramp input and you can verify your results using MATLAB. V. What will be the nature of the output response of this system (using Pole locations). Verify your system response by calculating the values of damping ratio and natural frequency of oscillations and verify your results using MATLAB. dont do matlab work An Electric Rail Transportation System The control of transportation systems is an interesting design and area.
