Abstract

Rudal adalah senjata militer yang membutuhkan presisi tinggi. Presisi rudal dipengaruhi oleh sistem kendali yang diterapkan. Penelitian ini bertujuan untuk meningkatkan presisi rudal melalui pengembangan sistem kendali Nonlinear Model Predictive Control (NMPC). NMPC dipilih karena kemampuannya dalam mengatasi sistem tak linier dengan banyak input dan output (MIMO), seperti model gerak rudal yang digunakan dalam penelitian ini. Oleh karena itu, disusun terlebih dahulu model matematika gerak rudal dengan enam derajat kebebasan. Untuk meningkatkan kemampuan NMPC dalam mengendalikan rudal, pendekatan baru diterapkan dengan mengintegrasikan Circular Error Probability (CEP) sebagai kendala terminal. Pendekatan ini bertujuan untuk mengatasi permasalahan posisi akhir rudal dengan mengintegrasikan aspek probabilistik dalam proses kendali. Untuk menjamin recursively feasibility, pendekatan soft constraints digunakan dalam perancangan kendala CEP. Simulasi pada berbagai skenario penargetan dilakukan untuk menganalisis pengaruh metode yang dikembangkan. Hasilnya, rudal berhasil dikendalikan ke arah target dan memenuhi kendala yang diberikan. Selain itu, penerapan kendala CEP berhasil meningkatkan presisi serangan rudal, dengan rata-rata radius kesalahan posisi akhir sebesar 0,3946 meter, dibandingkan dengan tanpa CEP yang menghasilkan rata-rata kesalahan sebesar 1,5872 meter. Pendekatan metode yang dikembangkan berpotensi untuk diterapkan pada berbagai sistem penargetan yang membutuhkan presisi tinggi, termasuk peluncuran roket satelit dan eksplorasi luar angkasa.

Missiles are military weapons that demand a high precision. The accuracy of a missile is determined by the effectiveness of its control system. This study aims to enhance missile precision through the development of a Nonlinear Model Predictive Control (NMPC) system. NMPC is selected due to its capability to handle nonlinear systems with multiple inputs and outputs (MIMO), such as the missile motion model utilized in this research. Consequently, a mathematical model of missile motion with six degrees of freedom is first constructed. To improve NMPC performance, a novel approach is proposed by integrating Circular Error Probability (CEP) as a terminal constraint. This approach aims to address the missile’s terminal position problem by incorporating probabilistic aspects into the control process. Additionally, to ensure recursively feasibility, soft constraints are employed in the design of the CEP constraint. Simulations under various targeting scenarios are conducted to analyze the impact of the developed method. The results demonstrate that the missile can be effectively guided toward the target while satisfying the imposed constraints. Furthermore, the application of the CEP constraint significantly enhances missile precision, achieving an average terminal position error radius of 0.3946 meters, compared to 1.5872 meters without the CEP constraint. The proposed method shows potential for application in various high-precision targeting systems, including satellite rocket launches and space exploration missions.
