Abstract

Web tension is related to controlling tension on the surface of the paper.Performance on the winder unit for the papermaking process requires smooth control, fast response and a minimum steady state error. So it need the right controller for this plant by paying attention to settling time and the desired natural frequency the sheet of paper. One optimal controller that appropriate to applied is Linear Quadratic Regulation (LQR). The results showed the LQR is able to produce optimal performance, where this control works by weighting the optimal Q and R matrices using trial and error methods.  The system response is able to reach a given setpoint of 0.5 N, and is able to minimize overshoot and maintain steady state, where the parameter values obtained are Ess = 0.0025 N, τ = 0.0732 seconds, tr = 0.4 seconds, ts = 0.1595 seconds, td = 0.0586 seconds, Mp = 0.05%, IAE = 0.03298 Keywords: Integral of Absolute Error (IAE), Linear Quadratic Regulator (LQR), Roll winder, Web tension.

Abstract

Transportation is a important thing for increasing of economyc development  in the world and the example a car. Car has important system that is suspension. Suspension is sustain of car and make sure comfort. Enjoy and comfort is a point  riding on the street. Ideal conditions when driving is the vehicle cabin does’nt shock on bumby roads. Suspension consists of two types, passive and active. In this paper use passive because easy and conventional modeling. Passive suspension is whics is still commonly used and  reduce vibration in the vehicle cabin when driving.  A controller is required for maintain the comfort cabin without vibration. LQR the optimal controller to solve regulator problem.  After being simulated the result is error -20.88meter and overhsoot 11.6%. PID controller is added for reduce error and overshoot. The result is error 0 meter overshoot 0% settling time 0.39, rise time 0.35 delay time 0.14. LQR-PID controller can reduce error and overshoot Keywords: LQR, LQR-PID , Suspension, Quarter Car

Abstract

Quadcopter is a type of unmanned aerial vehicle that has 4 rotor to fly. one of the most important and fundamental flying movements of the Quadcopter is the hover movement, that is the ability to fly hovering that is affected by the roll, Pitch and yaw angle  (rotation motion). The hover movement becomes an inner loop of the quadcopter system so it is necessary to maintain the stability. The Quadcopter also has light and small construction, that is makes the Quadcopter difficult to maintain its stability. To resolving the stability problem, conducted simulated test using MATLAB software for controller design capable of maintaining the quadcopter stability hover movement. The proposed controller is Sliding Mode Control (SMC), the SMC is a well-known controller for its robustness. From the test results, shows the SMC is able to reach a set point of 0.1 radians in less than 1 second and maintains the stability of the hover movement at the set point of 0.1 radians without any errors steady state and overshoot with settling time 0.319 for roll and pitch angle then 0.445 for yaw angle. Keywords : Hover, Quadcopter, Rotation Motion , Settling time, SMC, Stability
