Q 1. The aim of this task is to design a PID controller for a DC motor modelled in Simulink (or Octave, Octave Forge). Create a closed-loop system by using controller block, then tune the gains of PID controller using PID tuner to control the angular position of the DC motor. The motor has the following characteristics: J= 0.01 kg.m2, b= 0.1 Nms, k= 0.01 Nm/A, R=1.0 ohm, L= 0.5 H. Design criteria are: step input = 1.0 rad/sec, settling time less than 2 seconds, overshoot less than 3% and steady-state error less than 1%. You need to address the following: (a) Develop the block diagram of closed loop systems for the position control of DC motor using a PID controller. (b) Use Bode-plot to evaluate the performance of the system with regards to stability and response to a step input. (c) Investigate the effects of the P,I,D and PID parameters on the dynamic response of the system. (d) Explore the dynamic responses of PID controllers in terms of position control of a dc motor system with…

List some advantages of solid-state control.
