Is it effective to control the temperature within a Martian home as described in the questions? Suggestsome modifications on the control system, or even on the Martian home design to support your argument. Consider enhancing the process lags and the stability under sudden and/or permanent loadchanges. Reflect your improvements on the components of the closed loop system such as the control law, the actuator and the measurement system. Explain the effects of each improvement in details. B. A PID controller has KP = 3, KI = 1.2 s-1 , KD = 2 s and p(0) = 40%. Plot the controller output for the error signal given in Fig. 3. Suggest modifications to the gain values [roughly, not exact values] inorder to enhance the correction signal response. Explain the effect of your changeI have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?
