Abstract
Pemodelan matematika dari permasalahan yang nyata umumnya merupakan sistem dengan orde yang besar karena mengandung variabel keadaan yang banyak. Semakin banyak variabel keadaan, maka model matematika yang dihasilkan semakin mendekati kondisi sebenarnya. Suatu sistem juga memerlukan desain kontrol agar diperoleh sistem yang optimal. Sistem dan kontrol dengan orde besar sangat tidak efisien, sehingga perlu dilakukan proses modifikasi menjadi sistem dan kontrol yang sederhana. Metode reduksi yang digunakan adalah Balanced Truncation karena hasil reduksi memiliki sifat yang sama dengan sifat sistem awal yaitu stabil, terkontrol dan teramati. Metode kontrol yang digunakan adalah Linear Quadratic Regulator. Untuk membentuk sistem dengan desain kontrol orde kecil akan dilakukan dua cara yang berbeda yaitu reduksi pada sistem awal kemudian dibentuk desain kontrol dan desain kontrol pada sistem awal kemudian dilakukan reduksi. Hasil simulasi konduksi panas menunjukkan bahwa desain kontrol pada sistem dengan orde kecil memiliki sifat yang sama dengan sistem awal, yaitu stabil, terkontrol dan teramati. Selain itu hasil simulasi menunjukkan bahwa tahapan desain kontrol pada sistem awal yang kemudian dilakukan reduksi lebih efisien dalam waktu komputasi dan errornya lebih kecil daripada tahapan desain kontrol pada sistem yang telah direduksi.

Mathematical modeling of real problems is generally have a system with a large order because it contains many state spaces. Many state spaces used, the mathematical model that is produced is getting closer to the actual condition. A system also requires a control design to obtain an optimal system. Systems and controls with large order are very inefficient, so the modification process needs to changes into a simple system and control. The reduction method used is Balanced Truncation because the reduction results have the same properties as the initial system properties which are stable, controlled and observed. The control design method used is Linear Quadratic Regulator. To form a control design with a small order, two different steps will be carried out, that is reduction in the initial system, then formed a control design and control design are formed in the initial system, then reduction. The heat conduction simulation results show that the system with control design in a small order has the same properties as the initial system, which is stable, controlled and observed. In addition, the simulation results show that the control design stage in the initial system then reduced is more efficient in computational time and the error is smaller than the control design stage in the system that has been reduced.
